"安裝完 Visual Studio Code 並打開後,你會看到歡迎畫面。這個歡迎畫面提供了一些幫助性的連結,讓你可以快速開始使用 VS Code,包括連結到文件、教學和影片。

在螢幕的左邊,你會看到活動欄,它提供了對不同視圖的存取,例如檔案瀏覽器、搜尋、原始碼控制、擴充功能等。我們先從檔案瀏覽器視圖開始。

檔案瀏覽器視圖是你可以打開專案檔案並瀏覽檔案系統的地方。你也可以使用它來開啟資料夾並處理檔案。

現在,螢幕的右邊是編輯區域。這裡是你可以開啟檔案並開始編寫程式碼的地方。你可以同時開啟多個檔案,並將它們顯示在標籤頁中。

你還可以看到上方的搜尋欄,讓你能夠在檔案中搜尋特定的文字,並可以依檔案類型過濾搜尋結果。

最後,在螢幕的下方,你會看到狀態列。狀態列會顯示你當前專案的資訊,包括你在 Git 中所使用的分支、當前語言模式等資訊。"


這是第二部分的逐字翻譯。如果你需要繼續進行後續部分的翻譯,請隨時告訴我!

好的,接下來是第3部分的逐字翻譯。

3. 安裝 Python 擴充功能:Python 擴充功能是 VS Code 中最受歡迎的擴充功能,它提供了 Python 相關的功能,包括選擇 Python 解譯器和語法檢查。

影片時間範圍:06:09-07:48

原文內容(逐字翻譯)

"Now that you’ve got VS Code installed, we want to go ahead and install the Python extension. To do that, we’ll go over to the Extensions view, which you can access by clicking on the Extensions icon in the Activity Bar on the left-hand side.

This will open up the Extensions view, and from here you can search for the Python extension. Just type in ‘Python’ in the search box, and the first result that comes up will be the official Python extension from Microsoft. This is the one we want, so go ahead and click the Install button.

Once the extension is installed, you’ll see a confirmation in the status bar at the bottom of the screen that the Python extension is now active. You’ll also notice that you have some additional options available in the Command Palette, which you can access by pressing Ctrl + Shift + P on your keyboard."

翻譯內容

"現在你已經安裝了 VS Code,我們接著要安裝 Python 擴充功能。首先,我們要打開擴充功能視圖,你可以通過點擊左邊活動欄中的擴充功能圖示來進入這個視圖。

這樣會打開擴充功能視圖,在這裡你可以搜尋 Python 擴充功能。只需在搜尋框中輸入『Python』,第一個出現的結果就是 Microsoft 的官方 Python 擴充功能。這就是我們要的,所以請點擊安裝按鈕。

當擴充功能安裝完成後,你會看到在螢幕底部的狀態列顯示確認訊息,告訴你 Python 擴充功能已經啟用。你還會注意到在命令面板中有一些額外的選項,命令面板可以通過按下鍵盤上的 Ctrl + Shift + P 來開啟。"

好的,這是第4部分的逐字翻譯:

4. 設定 Python 解譯器:示範如何更改 Python 解譯器,並展示 VS Code 如何為專案創建特定的 .vscode/settings.json 設定檔。

影片時間範圍:07:49-09:44

原文內容(逐字翻譯)

"Now that the Python extension is installed, we want to make sure that VS Code is using the correct Python interpreter. To do that, we can go to the Command Palette by pressing Ctrl + Shift + P and then searching for ‘Python: Select Interpreter’.

This will bring up a list of available Python interpreters. Here, you can choose which version of Python you want to use for your project. You might have multiple versions of Python installed on your system, so it’s important to select the right one.

For example, I have Python 3.8 installed, and I can select that as the interpreter for this project. Once you’ve selected the interpreter, VS Code will automatically create a .vscode/settings.json file in your project folder. This file will store the Python interpreter settings specifically for this project.

You can also verify the selected interpreter by looking at the bottom left corner of the window, where the current interpreter will be displayed. If you ever need to change it, you can go back to the Command Palette and select a different one."

翻譯內容

"現在 Python 擴充功能已經安裝完成,我們要確保 VS Code 使用的是正確的 Python 解譯器。為此,我們可以按下 Ctrl + Shift + P 打開命令面板,然後搜尋『Python: Select Interpreter』。

這樣會顯示一個可用 Python 解譯器的清單。在這裡,你可以選擇你要在專案中使用的 Python 版本。你可能在系統中安裝了多個版本的 Python,所以選擇正確的版本非常重要。

例如,我安裝了 Python 3.8,並且可以將其選為此專案的解譯器。當你選擇了解譯器後,VS Code 會自動在你的專案資料夾中創建一個 .vscode/settings.json 檔案,該檔案將專門存儲此專案的 Python 解譯器設置。

你也可以通過查看視窗左下角來確認選擇的解譯器,當前的解譯器會顯示在這裡。如果你以後需要更改解譯器,隨時可以回到命令面板並選擇另一個解譯器。"


這是第四部分的逐字翻譯。如果你還需要更多後續內容的翻譯,隨時告訴我!

好的,這是第5部分的逐字翻譯:

5. 自訂介面(顏色主題和圖示):使用者自訂編輯器的外觀,選擇像是 Pre-Dawn 主題,並調整其他 UI 設定,如檔案圖示。

影片時間範圍:14:00-16:16

原文內容(逐字翻譯)

"Now that we’ve got the basics set up, let’s go ahead and make some customizations to the editor’s look and feel. First, I’m going to change the color theme of the editor.

To do this, I’ll press Ctrl + Shift + P to open the Command Palette, and I’m going to search for ‘Color Theme’. You’ll see a list of different color themes that you can choose from, and I’m going to select ‘Pre-Dawn’ for this project. You can select whichever theme suits you best.

Once you’ve selected the theme, the entire editor will change to reflect that color scheme. As you can see, the background and text have changed, and now it’s a lot darker, which helps with reducing eye strain during long coding sessions.

In addition to the color theme, you can also change the file icon theme. To do that, I’ll again go to the Command Palette and search for ‘File Icon Theme’.

This will give me a list of available icon themes. For this project, I’ll select the ‘Material Icon Theme’, which will change the way files and folders are displayed in the Explorer view. You can choose whichever icon theme you prefer, whether it’s ‘Material Icon Theme’, ‘Seti Icons’, or another theme."

翻譯內容

"現在我們已經完成了基本設置,接下來讓我們對編輯器的外觀做一些自訂。首先,我要更改編輯器的顏色主題。

為此,我會按下 Ctrl + Shift + P 打開命令面板,並搜尋『Color Theme』。你會看到一個可以選擇的顏色主題清單,我會選擇『Pre-Dawn』作為此專案的主題。你可以選擇任何你喜歡的主題。

當你選擇了主題後,整個編輯器的外觀就會根據該顏色方案進行更改。正如你所看到的,背景和文字已經改變,現在變得更暗了,這樣在長時間編程時有助於減少眼睛疲勞。

除了顏色主題外,你還可以更改檔案圖示主題。為此,我會再次進入命令面板,並搜尋『File Icon Theme』。

這會顯示一個可用圖示主題的清單。對於此專案,我會選擇『Material Icon Theme』,這會改變檔案和資料夾在檔案總管中的顯示方式。你可以根據自己的喜好選擇任何圖示主題,無論是『Material Icon Theme』、『Seti Icons』還是其他主題。"


這是第五部分的逐字翻譯。如果還需要更多後續部分,請告訴我!

好的,這是包含 "Ayu" 顏色主題的部分翻譯:

原文內容(逐字翻譯)

"In addition to Pre-Dawn, there’s also the ‘Ayu’ color theme, which is a bit more vibrant and has a different feel compared to Pre-Dawn. To change the theme to ‘Ayu’, I’m going to press Ctrl + Shift + P again, and this time, I’ll search for ‘Color Theme’ once more.

When the list of themes shows up, I’ll scroll down and select ‘Ayu’ from the list. As you can see, the editor will change once again to a brighter, more vivid color scheme. It has a bit of a warmer tone compared to ‘Pre-Dawn’, which some people might find more visually appealing.

The ‘Ayu’ theme is one of the options I like, but there are many others to choose from. You can always experiment with different themes to find one that works best for you."

翻譯內容

"除了 Pre-Dawn 主題外,還有‘Ayu’ 顏色主題,它比 Pre-Dawn 更加鮮豔,感覺也不同於 Pre-Dawn。要將主題更改為‘Ayu’,我會再次按下 Ctrl + Shift + P,然後這次再次搜尋‘Color Theme’。

當顯示出主題清單時,我會向下滾動並從列表中選擇 ‘Ayu’。如你所見,編輯器將再次改變為一種更明亮、更生動的顏色方案。與‘Pre-Dawn’相比,它有一點較溫暖的色調,有些人可能會覺得它視覺上更具吸引力。

‘Ayu’ 主題是我喜歡的選項之一,但還有許多其他選擇。你可以隨時嘗試不同的主題,找到最適合自己的那一款。"


這是關於 "Ayu" 顏色主題的逐字翻譯。如果還需要進一步的內容,隨時告訴我!

好的,這是第6部分 "Managing Code Formatting and Linters" 的影片操作內容逐字翻譯:


原文內容(逐字翻譯)

"Now that we have installed the Python extension, let’s move on to setting up code formatting and linters. We want our Python code to be clean and consistent, and there are a couple of tools that will help us do that.

First, we’re going to set up Black for auto-formatting. Black is a very popular code formatter for Python, and it will automatically format our code every time we save the file. So to install Black, we need to open the terminal in VS Code, which we can do by going to View and selecting Terminal, or by pressing Ctrl + \ as a shortcut.

Once the terminal is open, we’ll install Black by typing the following command:

pip install black

After Black is installed, we’ll need to set it as the default formatter for VS Code. To do this, we’ll press Ctrl + Shift + P to open the command palette and search for Preferences: Open Settings (JSON).

This will open the settings.json file. In the settings, we want to add the following line of code:

"python.formatting.provider": "black"

Now, Black is set up as the default formatter. The next step is to configure auto-formatting on save. So we’ll add another line to our settings.json file:

"editor.formatOnSave": true

This will make it so that every time we save the file, VS Code will automatically format it using Black. Now, let’s test it by creating a Python file, writing some unformatted code, and then saving the file. When we save it, VS Code will automatically format the code for us.

Next, we’ll set up linting using Pylint. Linting will check our code for errors and stylistic issues as we write it, helping us catch problems early.

To install Pylint, we’ll go back to the terminal and type:

pip install pylint

Once Pylint is installed, we need to configure VS Code to use it for linting. We’ll press Ctrl + Shift + P again to open the command palette and search for Python: Select Linter. This will bring up a list of available linters, and we’ll choose Pylint from the list.

Now, Pylint is set up. If we write some Python code that has a style or syntax issue, Pylint will highlight it with a warning or error in the editor. This will help us keep our code clean and avoid common mistakes."


翻譯內容

"現在我們已經安裝了 Python 擴展,接下來我們要設置代碼格式化和 Linter。我們希望 Python 代碼乾淨且一致,這裡有一些工具可以幫助我們做到這一點。

首先,我們將設置 Black 來進行自動格式化。Black 是一個非常受歡迎的 Python 代碼格式化工具,它會在每次保存文件時自動格式化我們的代碼。因此,要安裝 Black,我們需要在 VS Code 中打開終端,可以通過 View 選擇 Terminal 或按 Ctrl + \ 快捷鍵來打開。

終端打開後,我們通過輸入以下命令來安裝 Black:

pip install black

安裝完 Black 之後,我們需要將其設置為 VS Code 的默認格式化工具。為此,我們將按 Ctrl + Shift + P 打開命令面板,並搜尋 Preferences: Open Settings (JSON)

這會打開 settings.json 文件。在設定中,我們需要添加以下代碼行:

"python.formatting.provider": "black"

現在,Black 被設置為默認的格式化工具。接下來的步驟是配置保存時自動格式化。所以,我們將在 settings.json 文件中再添加一行代碼:

"editor.formatOnSave": true

這樣每次我們保存文件時,VS Code 都會自動使用 Black 來格式化代碼。現在,我們來測試一下,創建一個 Python 文件,寫一些未格式化的代碼,然後保存文件。當我們保存文件時,VS Code 會自動為我們格式化代碼。

接下來,我們將設置使用 Pylint 進行代碼檢查。Linting 會在我們寫代碼時檢查代碼中的錯誤和風格問題,幫助我們及早發現問題。

要安裝 Pylint,我們將回到終端,並輸入:

pip install pylint

安裝完 Pylint 之後,我們需要配置 VS Code 使用它來進行 linting。再次按 Ctrl + Shift + P 打開命令面板,搜尋 Python: Select Linter。這會顯示一個可用的 linter 列表,我們從中選擇 Pylint

現在,Pylint 設置完成。如果我們寫的 Python 代碼有風格或語法問題,Pylint 會在編輯器中高亮顯示警告或錯誤。這樣我們就能保持代碼的乾淨並避免常見錯誤。"

好的,這是第7部分 "Virtual Environments" 的影片操作內容逐字翻譯:


原文內容(逐字翻譯)

"Now, let’s move on to setting up virtual environments in VS Code. A virtual environment is an isolated workspace where we can install specific versions of libraries for a particular project. This ensures that our project dependencies are kept separate from global Python installations.

To start, we need to open the terminal in VS Code again. So, press Ctrl + \ or go to View and select Terminal. In the terminal, we’ll use the following command to create a virtual environment. Let’s create a directory for our project first, so we will use the command:

mkdir myproject
cd myproject

Once inside the project directory, we can create the virtual environment by typing:

python -m venv venv

This command will create a folder named venv in the project directory. Inside the venv folder, it will install a separate Python environment. Now, we need to activate this virtual environment. The activation process is slightly different depending on your operating system.

If you’re on Windows, you can activate the virtual environment with the following command:

.\venv\Scripts\activate

On macOS or Linux, the command is:

source venv/bin/activate

Once activated, you should see (venv) at the beginning of the terminal prompt, indicating that the virtual environment is active.

Now that the virtual environment is active, we can install dependencies that are specific to this project. For example, let’s install requests by typing:

pip install requests

After installation, we can see that requests is now installed within our virtual environment. To confirm that it’s installed in the virtual environment, we can run the following command:

pip freeze

This will list all the installed packages in the virtual environment. You should see requests listed here.

Next, let’s tell VS Code to automatically activate the virtual environment when we open the project. To do this, we need to add a configuration file to the project’s .vscode folder. In the terminal, we’ll type the following command:

mkdir .vscode

Now, let’s open the .vscode folder and create a new file named settings.json inside. In this file, we’ll add the following configuration:

{
  "python.pythonPath": "${workspaceFolder}/venv/bin/python"
}

This tells VS Code to use the Python interpreter from the venv folder. If you’re on Windows, the path will be different, so it will look like this instead:

{
  "python.pythonPath": "${workspaceFolder}/venv/Scripts/python.exe"
}

Now, VS Code will automatically detect and use the virtual environment when we open the project.

Whenever you work on this project, you need to make sure the virtual environment is activated, which will allow you to install and manage dependencies specific to this project. You’ll also want to make sure you’re using the correct Python interpreter by checking that (venv) appears in your terminal prompt.

And that’s it! You’ve successfully set up a virtual environment in VS Code."

"現在,讓我們繼續設置 VS Code 中的虛擬環境。虛擬環境是一個獨立的工作區,在這裡我們可以為特定的項目安裝特定版本的庫。這樣可以確保我們的項目依賴與全域的 Python 安裝保持分離。

首先,我們需要再次打開 VS Code 中的終端。所以,按下 Ctrl + \ 或者從 View 選擇 Terminal。在終端中,我們將使用以下命令來創建虛擬環境。我們首先創建一個項目的資料夾,所以我們使用命令:

mkdir myproject
cd myproject

進入項目資料夾後,我們可以通過輸入以下命令來創建虛擬環境:

python -m venv venv

此命令會在項目資料夾中創建一個名為 venv 的資料夾。這個 venv 資料夾裡將安裝一個獨立的 Python 環境。現在,我們需要啟動這個虛擬環境。啟動過程會根據操作系統的不同而有所不同。

如果你使用的是 Windows,則可以使用以下命令來啟動虛擬環境:

.\venv\Scripts\activate

如果你使用的是 macOS 或 Linux,則命令是:

source venv/bin/activate

啟動後,你應該會在終端提示符的開頭看到 (venv),表示虛擬環境已啟動。

現在虛擬環境已經啟動,我們可以安裝這個項目特有的依賴。例如,我們來安裝 requests,輸入以下命令:

pip install requests

安裝完成後,我們可以看到 requests 現在已經安裝在虛擬環境中。為了確認它是安裝在虛擬環境中的,我們可以運行以下命令:

pip freeze

這將列出虛擬環境中安裝的所有包。你應該會在這裡看到 requests

接下來,我們要告訴 VS Code 在我們打開項目時自動啟動虛擬環境。為此,我們需要在項目的 .vscode 資料夾中添加一個配置文件。在終端中,我們輸入以下命令:

mkdir .vscode

現在,讓我們打開 .vscode 資料夾,並在其中創建一個名為 settings.json 的新文件。在這個文件中,我們將添加以下配置:

{
  "python.pythonPath": "${workspaceFolder}/venv/bin/python"
}

這告訴 VS Code 使用來自 venv 資料夾的 Python 解釋器。如果你使用的是 Windows,路徑會有所不同,應該像這樣:

{
  "python.pythonPath": "${workspaceFolder}/venv/Scripts/python.exe"
}

現在,VS Code 在打開項目時將自動檢測並使用虛擬環境。

每次你在這個項目中工作時,你需要確保虛擬環境已啟動,這樣就能安裝和管理這個項目特有的依賴。你還要確保使用正確的 Python 解釋器,通過檢查終端提示符中是否顯示 (venv)

就這樣!你已經成功在 VS Code 中設置了虛擬環境。"

好的,這是第8部分 "Running Python Code with Keyboard Shortcuts" 的影片操作內容逐字翻譯:


原文內容(逐字翻譯)

"Let’s now set up a convenient way to run our Python code using a keyboard shortcut, rather than manually running the code in the terminal every time.

In order to do this, we’ll use a feature in VS Code called 'Tasks'. This will allow us to set up a custom task that runs our Python script with just a keyboard shortcut.

First, we need to open the command palette. To do that, press Ctrl + Shift + P or go to View and select Command Palette. Once the command palette is open, type ‘Tasks: Configure Task’ and select it from the list.

Now, VS Code will ask you to choose a task runner. We’re going to choose ‘Create tasks.json file from template’. You’ll see several task templates to choose from. Select the 'Others' option.

This will create a tasks.json file inside the .vscode folder in your project. If you don’t see the .vscode folder yet, just create it manually.

In the tasks.json file, we’ll configure a new task to run our Python code. Replace the default template with the following configuration:

{
  "version": "2.0.0",
  "tasks": [
    {
      "label": "Run Python Script",
      "type": "shell",
      "command": "python",
      "args": [
        "${file}"
      ],
      "group": {
        "kind": "build",
        "isDefault": true
      },
      "problemMatcher": []
    }
  ]
}

This configuration tells VS Code to use the python command and pass in the currently open file as an argument. It sets this task as the default build task, so it will run when we press the designated keyboard shortcut.

Now that we have the task set up, let’s assign a keyboard shortcut to it. Go to the File menu, select Preferences, and then choose Keyboard Shortcuts. In the search bar at the top, type ‘Tasks: Run Build Task’ and find the command. Next, click on the pencil icon next to it to edit the shortcut.

Press the keyboard combination you want to use. For example, let’s use Ctrl + Shift + R as the shortcut. After setting the shortcut, it will show up in the list.

Now, whenever you press Ctrl + Shift + R, VS Code will run your Python script using the currently open file in the editor.

This is a convenient way to run Python code without having to open the terminal and type the command each time. You can now execute your Python scripts with just one key combination."


翻譯內容

"現在,讓我們設置一個方便的方式來運行 Python 代碼,使用鍵盤快捷鍵,而不是每次都手動在終端中運行代碼。

為此,我們將使用 VS Code 中的一個功能叫做 'Tasks'(任務)。這將允許我們設置一個自定義任務,通過簡單的鍵盤快捷鍵運行我們的 Python 腳本。

首先,我們需要打開命令面板。為此,按 Ctrl + Shift + P 或者從 View 選擇 Command Palette。命令面板打開後,輸入 'Tasks: Configure Task' 並從列表中選擇它。

現在,VS Code 會要求你選擇一個任務運行器。我們將選擇 'Create tasks.json file from template'。你會看到幾個任務模板可以選擇,選擇 'Others'(其他)選項。

這將在你的項目中創建一個 tasks.json 文件,並放在 .vscode 資料夾中。如果你還沒有看到 .vscode 資料夾,請手動創建它。

tasks.json 文件中,我們將配置一個新的任務來運行我們的 Python 代碼。將默認模板替換為以下配置:

{
  "version": "2.0.0",
  "tasks": [
    {
      "label": "Run Python Script",
      "type": "shell",
      "command": "python",
      "args": [
        "${file}"
      ],
      "group": {
        "kind": "build",
        "isDefault": true
      },
      "problemMatcher": []
    }
  ]
}

這個配置告訴 VS Code 使用 python 命令並將當前打開的文件作為參數傳遞。它設置這個任務為默認的構建任務,所以當我們按下指定的鍵盤快捷鍵時,它會運行。

現在,我們已經設置好了任務,讓我們為它分配一個鍵盤快捷鍵。進入 File 菜單,選擇 Preferences,然後選擇 Keyboard Shortcuts。在頂部的搜索框中,輸入 ‘Tasks: Run Build Task’ 並找到該命令。接著,點擊它旁邊的鉛筆圖標來編輯快捷鍵。

按下你想要使用的鍵盤組合。例如,讓我們使用 Ctrl + Shift + R 作為快捷鍵。設置完快捷鍵後,它會顯示在列表中。

現在,每當你按下 Ctrl + Shift + R,VS Code 會運行你的 Python 腳本,使用當前在編輯器中打開的文件。

這是一個方便的方式來運行 Python 代碼,無需每次打開終端並輸入命令。你現在可以通過一個鍵盤組合來執行你的 Python 腳本。"

好的,以下是第9部分 "Git Integration and Version Control" 的影片操作內容逐字翻譯:


原文內容(逐字翻譯)

"Now let’s dive into Git integration within Visual Studio Code. First, let’s make sure that Git is properly installed on your system. You can check if Git is installed by opening the terminal and typing git --version. If you see a version number, Git is installed. If not, you’ll need to install it.

Once Git is installed, let’s go back to VS Code. Open the command palette by pressing Ctrl + Shift + P or selecting Command Palette from the View menu. In the command palette, type ‘Git: Clone’ to clone a repository from GitHub or any other Git server.

When you select the 'Git: Clone' command, it will ask you for a repository URL. Enter the URL of the repository you want to clone. For example, you can clone a GitHub repository by entering its URL here.

Once the repository is cloned, VS Code will prompt you to open the folder. Click Open to open the repository in VS Code. You’ll now see your project files in the Explorer panel on the left.

Now, let’s look at the source control panel. On the left-hand side of VS Code, you’ll see an icon that looks like a branch. This is the Source Control panel, where you can manage your Git repository. Click on it to open the panel.

In the source control panel, you’ll see the changes made to your project. If you modify a file, it will show up here as a change. To stage a change, hover over the file, click the plus icon, or click the ‘+’ sign to add it to the staging area.

Once you’ve staged your changes, you can commit them. In the message box at the top, enter a commit message, then click the check mark to commit your changes. The commit is now part of your Git history.

To push your changes to GitHub, click on the ellipsis (...) in the source control panel and select ‘Push’. VS Code will ask for your GitHub credentials if this is the first time you’re pushing. Enter your username and password, or use a personal access token for authentication. After that, your changes will be pushed to the repository on GitHub.

To pull changes from the remote repository, click on the ellipsis again and select ‘Pull’. This will fetch the latest changes from the remote repository and update your local copy.

That’s a basic overview of how to use Git within Visual Studio Code. You can also manage branches, view the history of commits, and use more advanced Git features directly within the editor."


翻譯內容

"現在,讓我們深入了解 Visual Studio Code 中的 Git 集成功能。首先,讓我們確保 Git 在你的系統上正確安裝。你可以通過打開終端並輸入 git --version 來檢查 Git 是否已安裝。如果你看到版本號,則說明 Git 已經安裝。如果沒有,你需要安裝它。

一旦 Git 安裝完成,我們回到 VS Code。打開命令面板,按 Ctrl + Shift + P 或者從 View 菜單中選擇 Command Palette。在命令面板中,輸入 ‘Git: Clone’ 來克隆來自 GitHub 或任何其他 Git 伺服器的倉庫。

選擇 'Git: Clone' 命令後,它會要求你輸入倉庫的 URL。輸入你要克隆的倉庫 URL。例如,你可以輸入 GitHub 倉庫的 URL 來進行克隆。

一旦倉庫被克隆,VS Code 會提示你打開該文件夾。點擊 Open 來在 VS Code 中打開該倉庫。你現在可以在左側的資源管理器面板中看到你的項目文件。

現在,讓我們來看一下源代碼控制面板。在 VS Code 的左側,你會看到一個看起來像分支的圖標。這就是源代碼控制面板,在這裡你可以管理你的 Git 倉庫。點擊它來打開面板。

在源代碼控制面板中,你會看到你對項目所做的變更。如果你修改了某個文件,它會顯示在這裡,作為一個變更。要暫存這個變更,只需將鼠標懸停在該文件上,點擊加號圖標,或點擊 ‘+’ 標誌將其添加到暫存區。

一旦你暫存了變更,你可以提交它們。在頂部的消息框中輸入提交信息,然後點擊勾號圖標來提交你的變更。這個提交現在成為了你的 Git 歷史的一部分。

要將你的變更推送到 GitHub,請點擊源代碼控制面板中的省略號(...),並選擇 ‘Push’。如果是第一次推送,VS Code 會要求你輸入 GitHub 賬號的憑證。輸入你的用戶名和密碼,或者使用個人訪問令牌進行身份驗證。之後,你的變更將被推送到 GitHub 上的倉庫。

要從遠端倉庫拉取變更,請再次點擊省略號,並選擇 ‘Pull’。這會從遠端倉庫抓取最新的變更並更新你本地的副本。

這就是如何在 Visual Studio Code 中使用 Git 的基本概覽。你還可以直接在編輯器中管理分支,查看提交歷史,並使用更多進階的 Git 功能。"

影片逐字稿

Summarize the following content in 5-10 bullet points with timestamp if it's transcript. Title: "Visual Studio Code (Windows) - Setting up a Python Development Environment and Complete Overview" Transcript: "(00:00) hey there how's it going everybody in this video we're gonna be learning how to install Visual Studio code and set up a Python development environment we're also going to go over the different features of this editor and see why it's so nice for Python development so we'll cover how to easily switch between editors how to debug applications how git integration works look at unit testing capabilities and a few other things so I've had a ton of comments and requests to cover vs code and it just seems like so many people are switching (00:26) over to it I don't know how many of you all listen to talk Python podcasts with Michael Kennedy but at the end of every show he always asks us guess what editor or IDE they prefer to use and it used to be pretty mixed but now I just feel like I hear vs code so often on there that I figured I had to take some time out to try this and I've got to say so far I'm really impressed with this editor now I wouldn't doubt if you all see me using this from here on out in my videos so with that said let's go ahead and get (00:53) started and see how to set this up and I'll show you what I like so much about this now I ran into some differences between how this works on Windows and Mac so I decided to just make one video specifically for Windows and one specifically for Mac so this video will be covering how to use vs code on Windows but if you're using a Mac then I'll be sure to leave a link to that video in a description section below so firs t of all let's go ahead and install Visual Studio code so I've got their website pulled open here in my browser (01:20) and that is at code Visual Studio com now Visual Studio code is different from Visual Studio which is a full on IDE vs code is a lighter-weight editor that can be extended with plugins for whatever we need so be sure to search for Visual Studio code and not just Visual Studio I'll also have a link to this page in the description section below now vs code is free so we don't nee d to buy anything we just need to download it and install it so I'm just going to download it from the website here so I'll click on download and then it (01:53) choose your operating system I'm on a Windows here and now this should download automatically ok so once that is downloaded I'm just going to run that executable and this is just like any other software installation wizard we'll have to accept some terms here pick our install location I'll go ahead and create a desktop icon for this as well and let's just continue on and finally I will install and once that's installed then I will open up visual studio code okay so now that that's finished I'm just going to check (02:26) this here that says launch Visual Studio code and finish that and now it should launch vs code for the first time here so this might take a sec to pop up okay so when we first run vs code it's going to open they're getting started page in the browser and also it's going to show us their welcome screen here wit e here is the Explorer and if we click on that then this is where we can open our directories and files we don't have anything open right now but we have the option to open a project folder and we'll do that here in just a second so the second option here this is for search so this is where we can do our (03:59) finds and replace and we can do these within multiple files and the third icon here is the git integration which is the source control and we're gonna take a look at this in a bit and se within the extensions here but I'm just going to close that for now and now we're going to look at the popular extensions here so the extension that we're really after right now is this Python extension and this is the most popular extension on vs code by far so if I sort the extensions by popularity so right now if we go to show popular extensions then it's already sorted by install count but we can also sort by rating a name if we wanted to as well so (06:09) we can see here at the top we have m I'm going to select deselect to show the welcome page on (07:48) startup and now I'm going to open up my python script okay so we get a few pop-ups down here this one says that we can change our Python interpreter and this one says that we don't have a linter installed now I'm probably going to get these pop-ups a good bit but I'm just going to ignore them for now and we will take a further look at these whenever we actually do linting but for now I'm gonna have to keep just exiting those out ee how to make it more simple in just a bit but for now if we look at my output down here then we can see that I'm using Python 3 7 that are printed out right there and then it prints out the location where that is here on my machine and also it (10:02) printed out those greetings ok so what if we wanted to change our Python interpreter so there are a couple of different ways that we can do this so if we look at the blue bar at the bottom of the page then in the bottom left it shows us which Pyt e that now when I changed my interpreter you may or may not have noticed that vs code created a folder inside of my project directory here called dot vs code and that directory has a Settings dot JSON file so these are settings for our specific current workspace so let me open this up and we can see that it set our Python a path within the settings JSON file but what if we wanted to use a certain Python interpreter by default (12:19) for every project because right now this is just this specific -dawn now somebody has actually put together a pre-dawn 4 vs code as well (14:00) and I'm glad that they did because I like that color theme so that's what I'm going to use and it's this one here pre-dawn theme kit this pre-dawn Twilight I'm not sure what that is but this is the one that looks like the sublime text version so I'm going to install that and then click on that to use pre-dawn now if I go back to my script then we can see for those of you have seen my videos before this likely looks I like this one because it gives a nice indicator of closed and open folders here on within your file explorer over here okay so I think those setting changes look pretty good for both our color theme and for our file (16:16) icons so right now we're actually implicitly changing our global user settings by changing our color themes and all of that but there are a ton of other settings that we can change that we haven't seen yet so if we want to see all of the settings that we can change then we e changed the zoom level this startup editor is because I said that I don't want to see the welcome screen when I log in we have the color theme here and the icon theme here as well now I have some other preferred settings that I'll show in just a bit now I do wish that they showed the default settings by default when we open up our settings as well because I feel like someone who's new to (18:18) v/s code might not know what settings they can and can't change so it'd be nice to see those defaul n we can always click on this pencil (19:59) icon over here and the gutter that says edit when I click on that it gives us the options that we can use so we can either use UI or JSON so that is a nice touch there and it says I have to save and retry in order to save that so I changed that to JSON now I'm also going to let's see come down here a little bit and I want open default settings set the true as well we can see that the comment here says controls whether opening settings also opens an ed e into my settings and now I want to put the full path to the version of Python that I want to use by default so in order to do this I think the best way to grab this would just be to open (22:21) my integrated terminal here and you can do that with control tilde and now I'm gonna do a command of where Python and this should show me okay so that didn't work there let me see if the Python command is running there okay so that is so I can do import sis and then do sis dot executable and that will that is because we are zoomed in to the here so that size 16 font actually looks pretty large the reason we're zoomed in is so that we can see everything else here in the editor like the sidebar and things like that now on your machine you might not need to zoom in the only reason I'm doing that is because I'm recording this video and I want (24:46) everybody to be able to see now I'm also using a source code Pro here as my font for the editor and for the debug terminal now if you want to use th 23) this so I'll be sure to leave a link to that in the description section below as well if anyone is interested but basically we can just say Python whoops let me spell that right Python - M and that will run a module and the module we want to run is ve and V and now we can pass in our arguments to that module and the arguments we want our the virtual environment name and the virtual environment name I'm just going to call ve and V as well so if I run that then it might take a second to create tivate that environment and all new terminal sessions as well so I think that's a really nice feature so if I open up terminal here let me close down the one I currently have by (28:37) clicking this trashcan and kill terminal let me open up another one and when I open that we can see that it automatically came in and ran that activate script on that virtual environment so if I clear my screen here we can tell that the virtual environment is active because we have V and V over here in a so if we e request library itself so we can see exactly how that method was written so I think that's a very nice feature now if we don't want to completely open up that file where that method exists then we can click on peak definition and that will just show us a little peak here so we can see the get method here within this little window but when we close that or write back to (31:02) our file so I think that intellisense is very useful for giving you information like that so let me actually go to my (32:57) auto pep eighth installed would you like to install that as your formatter and it also suggests some other popular formatters here too such as black and why a PF now I'm going to use black here but you can use auto pepe if you'd like I actually don't really know the differences between those two but I saw on Kenneth writes his blog that he was using black so I'm gonna give it a shot and see if I notice any differences or not okay so now with that formatter installed then we should be abl l of these here so format on paste format on save I want format on save so anytime I save it'll just auto format my code for me and that's a setting that I think is very (35:24) useful so that we don't have to keep manually doing that and the auto formatting and vs code really is great not only does it do Python like we have set up here but it will also auto format for JSON and other languages as well and those are all things that usually require additional packages with editors like sublime tex ur own so if this pop-up wasn't open here I'm just going to close it one more time then we can search using our command palette I'm just going to type in linting and now I'm gonna choose run linting when I try to run linting it's going to pop up with that pop-up so now I'm going to install that and it'll install pilant (37:47) and you can use other linters as well but I think that pilant is a and nice default linter to use I haven't really tried any of the other ones but pilant has been good for hen that might be a mistake so usually we don't want those so with that pointed out I'm just going to get rid of that to clean up the code and there we go okay so now let me show you an extension that I like to use that makes running Python code a bit easier so so far we've been right-clicking and selecting run code in terminal every time we want to run our Python code but I'm not the biggest fan of that I'd rather have an easy keyboard shortcut (39:58) that does this for us and also I don't lik ht here so it says that we're using Python 3 7 and that we got our status code of 200 but the Python (41:53) interpreter that it's using is the default interpreter for my system so this is the global version of Python and I do have requests installed in that global version of Python but if I didn't have requests installed then that would fail even though I do have requests installed in my virtual environment so we want to set this up to use our virtual environment instead of our global Python to ange here now you don't have to make these changes but this is my preferred settings so I can do a code runner and again I can hit control space to make this autocomplete for me and I want to change this clear previous output I want to change that to true because I don't like a lot of previous (44:23) runs of my script taking up all of my screen okay and now the last thing that I'm going to change here is code runner show execution message that is true by default I want to set this equal to fals was that people would always ask me how to do input within sublime and it was actually hard to do within sublime and I would always just recommend against it I would just recommend instead using the terminal so to write your script within sublime and then use the terminal now within vs code if we want to use input then it's kind of the same process but now we have a terminal built in so I'm going to just get rid of my code here everything except the imports and now (46:44) I'm just going to use t I want to track so I'm just going to click on my project the one (48:31) that I've been working in so once we do that it's going to now put in all of the files here that are untracked now it looks like we have a lot it says there are over 3,000 but most of these are from our virtual environment and we usually don't want to even track our virtual environment so to ignore our that directory we just need to create a dot git ignore file and add that to what we're tracking with git within my folder e we could hover over them and just click on the plus icon beside each file so if I do that with git ignore we can see that that got staged or if we wanted to stage all of the changes then we can just click the extra options up here at the top right (50:45) and then if I scroll down here I can go to stage all changes so if I do that then we can see that now our script pi is staged as well so now to commit we can just click on this check mark here to commit and now it's going to ask us for a comm the integrated terminal so I'm gonna save that and now let me close down the terminal that we had before and now open that back up and now we should be using git bash instead and we can see that it still activates that virtual environment now my text is a little large here so I'm running on to a new line but it's large enough just so you all can see but normally this would all be on one line here so let me clear (53:08) this out just by running clear there and now I can run those get configurati nd now this is our new code over here on the right so the red is saying hey you removed all of this stuff here that's what was last committed it's now gone and the green over here is saying oh and this is what was added this we didn't have this here before and now we do so if that diff looks good then you can simply stage your changes you want to close down the diff here so we staged the changes here it says that it's modified now I can commit that and as a (55:25) commit message here I'll just source control tab I can simply click here with the extra options and I'm going to select this command here (57:20) push - and when I click push - it says well where do we want to push this we have this thing called origin here at this URL and that is what got added when we ran that command that get gave us or that github gave us so if I run that then it's going to push that up to github now it's asking me to log in here so let me log in really quick with my username and password it's been a wh the debug tab over here in our activity bar and now let me make this a little bit larger here we can see that it says we don't currently have any configurations but if I click the little gear icon here then we can see some different configurations so we (59:35) have Python file we have module Django flask so you can set up these configurations to where it'll run you know your main flask app from there and you can also specify ports and stuff like that for this video we're just going to look at ore interactive then we can also use let me make this a little smaller over here we can also use the debug console and use this to inspect anything we'd like so I'm gonna click on our additional views here click on debug console and within the debug console we can just use this like an interactive Python prompt so if I wanted to see the value of r dot okay then i could just run that and we can see that it gives us this feedback of exactly what these values are equal to at this (1:01:57) point in ing support that they have built in to vs code and I'm really loving their attention to detail and how they covered so many different aspects (1:03:37) of helping us manage our code as easily as possible so having the built-in support for all this stuff is definitely a nice addition that you're not gonna find in most other editors so to show some unit testing I'm going to close down my current project and I'm going to open up a different project that has some sample unit tests so I'm going to cl to say to install that for our default Python as well so that we stop seeing those pop-ups okay so now let me open up both of these unit tests here okay so now that we have some unit tests available here let's run open up our command palette and now let's type in discover tests and when we run discover tests then it's (1:06:11) going to come up with this pop-up here that says enable and configure test framework so I'm going to click on that and now it's going to ask us what unit testing framewor now we can see it says three tests pass one test failed so if I click on this status down here in the bottom then it'll ask us what we want to do so we can run all of the tests again we can simply just run the failed test which is a nice feature as well or we can view the test output if I look at the test output here then we can see it ran for test one of them failed and it failed because of an assertion error that 15 is not equal to 10 and that it failed on line 8 so it shows us exactly where o show you in this video and it's only going to take one second so I have some other preferred settings that I haven't shown in this video and (1:10:04) most of them are settings for changing how they editor looks in full-screen send mode and will allow me to run code without too much other stuff getting in the way and I want to show you these settings so that you can see exactly how I'm gonna have my vs code set up if you see me using this editor in future videos because I get a lot of question open up Zen mode here and we can see how I have this set up it's you know takes away our activity bar the blue bar down here at the bottom so it's just a lot more clean and the nothing is distracting us from the code itself and we can still run code by just clicking up here and clicking run code now it's telling me it (1:12:14) can't find the specified path and the reason is because like I was saying these are my Mac settings so the path that I have set up for my Mac is this is more of a Linux cally how to do anything within vs code that we'd want to do so we have all of the multi cursor selection here file management search and replace things like that so that is a nice reference there if you would like to learn any of those keyboard shortcuts okay so I think that is going to do it for this video I hope you all found this video helpful especially if you're trying to switch over to vs code for your Python development so personally I think they really knocked it "

如果只是分析 Excel 裡的數據(而不修改 Excel 本身),可以用 Pandas

Pandas 並非專為 Excel 開發的,而是通用的數據分析工具

 ❌ Pandas 並非專為 Excel 開發的,而是通用的數據分析工具。

📌 Pandas 的原始目的

Pandas 是 Python 的 數據分析與處理 函式庫,最初是為了 處理結構化數據(如表格、時間序列、資料庫資料) 而開發的,並非特別為 Excel 設計。

📄 Pandas 與 Excel 的關係

Pandas 支援 Excel 檔案格式(如 .xls, .xlsx),但它也能處理其他格式,例如:

  • CSV(逗號分隔值 .csv
  • JSON(.json
  • SQL 資料庫
  • HTML 表格
  • Parquet(大數據格式)
  • HDF5(科學計算格式)

📌 Pandas 能讀寫 Excel,但它不是 Excel 的擴充工具,而是更強大的數據處理工具。


🔍 與 Excel 相關的 Pandas 功能

雖然 Pandas 不是專為 Excel 設計的,但它內建了對 Excel 的支援:

功能 Pandas 方法
讀取 Excel pd.read_excel()
寫入 Excel df.to_excel()
讀取 CSV(Excel 也能開啟) pd.read_csv()
轉換 DataFrame 為 Excel 格式 df.to_excel('file.xlsx', index=False)

🔑 結論

Pandas 是數據處理工具,不是 Excel 附屬工具。
Pandas 可以讀寫 Excel 檔案,但也能處理其他格式(CSV、SQL、JSON 等)。
如果主要在 Excel 工作,OpenPyXL 可能更適合,Pandas 則適合進行數據分析與統計運算。

如何處理 Excel 資料但不依賴 Excel 介面

 📌 如何處理 Excel 資料但不依賴 Excel 介面?(Pandas、OpenPyXL、PyExcel)

當我們談到 「處理 Excel 資料但不依賴 Excel 介面」,指的是 直接操作 Excel 檔案,而不需要開啟 Excel 軟體。這種方法的關鍵是 使用 Python 的程式庫(如 Pandas、OpenPyXL、PyExcel)來讀取、修改、儲存 Excel 資料,而不是透過 Excel 軟體本身來操作


🛠 1. 為何要處理 Excel 資料但不依賴 Excel?

有些情境下,我們不希望或不能使用 Excel 軟體本身,例如:

  • 批量處理大量 Excel 檔案(數百個 Excel,手動開啟太慢)
  • 在伺服器環境自動處理 Excel 檔案(伺服器沒有 Excel 軟體)
  • Excel 介面太慢,資料過大,開啟 Excel 會卡頓
  • 需要 Python 來做更高效能的數據分析
  • Excel 版本不同,可能有不相容問題

在這些情境下,我們可以使用 Pandas、OpenPyXL 或 PyExcel 來直接讀取、寫入 Excel 檔案,而不需要開啟 Excel 軟體。


📚 2. 主要 Python Excel 函式庫與它們的角色

函式庫 用途 適用情境
Pandas 讀取、修改、分析 Excel 資料 適合數據處理、統計分析
OpenPyXL 讀取、修改 Excel 檔案(.xlsx) 適合編輯儲存格、寫入新資料
PyExcel 多種 Excel 格式轉換(.xls、.xlsx、.ods) 適合需要支援多種 Excel 格式的場合

📌 3. 具體實作:如何不依賴 Excel 介面來處理 Excel 資料?

🔹 方法 1:用 Pandas 讀取與分析 Excel

Pandas 主要用來讀取與分析 Excel 資料,而不是修改 Excel 檔案的格式。

📌 讀取 Excel 檔案:

import pandas as pd

# 讀取 Excel 檔案(不會開啟 Excel 軟體)
df = pd.read_excel("data.xlsx")

# 顯示前五列
print(df.head())

💡 重點:Pandas 可以直接讀取 Excel 檔案並轉成 DataFrame,不用開啟 Excel。

📌 資料篩選與處理:

# 篩選出年齡大於 30 的人
df_filtered = df[df["年齡"] > 30]

# 重新存成 Excel
df_filtered.to_excel("filtered_data.xlsx", index=False)

💡 重點:Pandas 能進行數據篩選並儲存為新的 Excel 檔案,這一切都不用開 Excel 介面。


🔹 方法 2:用 OpenPyXL 修改 Excel 檔案

Pandas 主要用來分析 Excel 內的資料,但如果你需要 修改 Excel 儲存格,如:

  • 改變某個儲存格的值
  • 新增工作表
  • 修改儲存格的顏色、格式

這時你需要 OpenPyXL

📌 讀取 Excel 並修改儲存格

from openpyxl import load_workbook

# 讀取 Excel 檔案
wb = load_workbook("data.xlsx")
ws = wb.active  # 取得目前的工作表

# 修改 A1 儲存格的值
ws["A1"] = "新標題"

# 存回 Excel
wb.save("data_modified.xlsx")

💡 重點:這段程式碼改變 Excel 檔案的內容,但不需要開啟 Excel 軟體。

📌 新增一個新的工作表

ws_new = wb.create_sheet("新工作表")
ws_new["A1"] = "這是新的工作表"
wb.save("data_modified.xlsx")

💡 重點:這讓你可以自動化地新增 Excel 工作表,完全不依賴 Excel 介面。


🔹 方法 3:用 PyExcel 轉換 Excel 格式

PyExcel 主要用於轉換 Excel 檔案格式(如 .xls.xlsx)。

📌 將 xls 轉換成 xlsx

import pyexcel

pyexcel.save_as(file_name="old_file.xls", dest_file_name="new_file.xlsx")

💡 重點:這樣可以在不開啟 Excel 的情況下,將不同格式的 Excel 檔案轉換。


⏳ 4. 這樣做有什麼好處?

1️⃣ 效能更快:不需要開啟 Excel 軟體,程式可直接處理數據
2️⃣ 適合批量作業:可以同時處理成百上千個 Excel 檔案
3️⃣ 可在伺服器運行:許多伺服器上沒有安裝 Excel,但仍可使用 Python 操作 Excel 檔案
4️⃣ Python 能進行更複雜的數據處理(如機器學習、統計分析)


🔍 5. 總結:何時選擇哪種方式?

需求 適合的 Python 函式庫
快速讀取與分析 Excel 數據 Pandas
修改 Excel 儲存格內容 OpenPyXL
新增 Excel 工作表、變更格式 OpenPyXL
轉換 Excel 檔案格式 PyExcel

🎯 6. 結論:你該如何開始?

✔ 如果你主要是 分析 Excel 資料學 Pandas 就足夠
✔ 如果你需要 修改 Excel 檔案,如變更儲存格內容,學 OpenPyXL
✔ 如果你需要 格式轉換(例如 .xls.xlsx),學 PyExcel

這些工具都不需要開啟 Excel 軟體,讓你可以 高效處理大量 Excel 檔案!🚀

為何 C++ 被認為是高效能語言?

C++「高效能」是指什麼?為何 C++ 被認為是高效能語言?

C++ 之所以被認為是「高效能(High Performance)」的程式語言,主要原因來自於 運行速度快、資源管理靈活、低階控制能力強。它廣泛應用於需要極致效能的領域,如 遊戲引擎、嵌入式系統、金融交易、影像處理、機器學習 等。


🔹 C++ 為何高效能?

1️⃣ 編譯語言(Compiled Language)

C++ 屬於 編譯語言(Compiled Language),這意味著:

  • 程式碼先被轉換成機器碼(CPU 可直接執行)
  • 不需要額外的執行環境(如 Python 需要解釋器)
  • 執行速度快,比 解釋語言(Interpreted Language,如 Python、JavaScript) 更有效率

💡 舉例:
Python 需要透過「解釋器」逐行執行,而 C++ 已經是機器碼,執行時效能極高。


2️⃣ 低階記憶體控制

C++ 允許直接操作記憶體(使用 newdeletemallocfree),不像 Python、Java 依賴 垃圾回收機制(Garbage Collection, GC)

優勢

  • 記憶體管理靈活(可以手動調整資源分配)
  • 避免額外的 GC 耗時(GC 會在不預期的時候執行,影響即時性)
  • 適合低階系統開發(作業系統、驅動程式、嵌入式系統)

💡 舉例

int* ptr = new int(10);  // 手動配置記憶體
delete ptr;              // 釋放記憶體(避免記憶體洩漏)

而 Python 則完全依賴 自動垃圾回收

x = 10  # Python 會自動管理記憶體,不需要手動刪除變數

3️⃣ 不需要虛擬機(如 Java)

Java 需要透過 JVM(Java Virtual Machine) 運行程式,這帶來跨平台優勢,但也會:

  • 消耗額外的記憶體
  • 有額外的執行時間(Overhead)
  • 可能觸發 GC(垃圾回收),導致程式延遲

C++ 是 直接編譯成本機器碼,不需要額外的虛擬機,執行速度更快。


4️⃣ 內存局部性(Memory Locality)好

C++ 可以使用 結構體(struct)和陣列(array) 來確保資料存放在 連續的記憶體區塊,提高 CPU 快取(Cache)的命中率,降低存取時間。

💡 舉例

struct MyStruct {
    int a, b, c, d;
};

這樣的記憶體存放方式 比 Python、Java 的物件存放方式更有效率


5️⃣ 內聯函式(Inline Function)降低函式呼叫開銷

C++ 允許使用 inline 修飾符將函式 直接嵌入程式碼,避免函式呼叫的額外成本。

💡 舉例

inline int square(int x) { return x * x; }

這比一般的函式呼叫 更快,因為省去了 額外的呼叫開銷(Function Call Overhead)


6️⃣ 直接使用 SIMD(單指令多資料流)和多執行緒

C++ 提供:

  • SIMD 指令集(如 SSE、AVX)→ 用於高效能數據運算(如影像處理、機器學習)
  • 多執行緒(Multithreading) → 提供高效能並行計算

💡 舉例(OpenMP 多執行緒)

#include <iostream>
#include <omp.h>

int main() {
    #pragma omp parallel
    {
        std::cout << "Hello from thread " << omp_get_thread_num() << "\n";
    }
    return 0;
}

這樣的並行運算在 Java、Python 需要額外的庫來支援,而 C++ 內建支持。


🔹 什麼應用需要 C++ 的高效能?

即時運算

  • 遊戲開發(Unity、Unreal Engine)
  • VR/AR
  • 影像處理(OpenCV)
  • 機器學習推論(TensorRT)

低階開發

  • 作業系統(Windows、Linux Kernel)
  • 驅動程式(NVIDIA、AMD 驅動)
  • 嵌入式系統(Arduino、Raspberry Pi)

金融高頻交易

  • 股票自動交易(HFT)
  • 區塊鏈技術

🔹 總結

優勢 原因
🚀 直接編譯為機器碼,無需解釋或虛擬機
🧠 記憶體管理靈活 手動管理記憶體,避免垃圾回收帶來的效能問題
🏎 內存局部性強 資料存取方式可優化,提升 CPU 快取命中率
🎯 適合高效能計算 支援 SIMD、並行運算、多執行緒

如果你對 C++ 在某些特定領域的應用有興趣,比如 遊戲開發、機器學習、金融交易,可以深入學習 C++ 的高效能技術! 🚀

各種程式語言的類別(Classes)比較

 📌 各種程式語言的類別(Classes)比較:VBA、Python、Java、C++

不同程式語言對於 類別(Class) 的支援程度有所不同。以下是 VBA、Python、Java、C++ 在類別的應用上有哪些 相似點與不同點


🔹 什麼語言支援類別(Class)?

語言 是否支援類別(Class) 是否完全物件導向(OOP)
Python ✅ 支援 🟢 完全物件導向
Java ✅ 支援 🟢 完全物件導向
C++ ✅ 支援 🟡 既支援 OOP,也支援程序式
VBA 🟡 部分支援 🔴 主要是程序式,但可以模擬 OOP
JavaScript ✅ 支援(ES6+) 🟢 支援物件導向,但也可當作函式式語言
C(ANSI C) ❌ 不支援 🔴 純程序式語言

完全物件導向(OOP)語言 → Python、Java
🟡 可用 OOP,但不是強制 OOP → C++、JavaScript、VBA
🔴 沒有內建類別機制 → C(但可以用 struct 和函數模擬)


🔹 各語言的類別語法比較

以下是 VBA、Python、Java、C++ 的類別語法比較,以「汽車(Car)」類別為例。


🔹 Python:動態語言,支援 OOP

Python 是 完全物件導向 的語言,所有東西(甚至整數、函數)都是物件。

class Car:
    def __init__(self, brand, color):
        self.brand = brand  # 屬性
        self.color = color  # 屬性

    def drive(self):
        print(f"{self.color} 的 {self.brand} 正在行駛!")

# 創建物件
car1 = Car("Toyota", "紅色")
car1.drive()  # 輸出:紅色 的 Toyota 正在行駛!

Python 特點:

  • 動態型別(變數類型可變)
  • 支援多重繼承
  • 物件可直接修改屬性
  • 簡潔易讀,沒有強制變數類型宣告

🔹 Java:強型別、純物件導向

Java 是 純物件導向 的語言,所有東西都必須定義在類別內。

class Car {
    private String brand;
    private String color;

    // 建構子
    public Car(String brand, String color) {
        this.brand = brand;
        this.color = color;
    }

    // 方法
    public void drive() {
        System.out.println(color + " 的 " + brand + " 正在行駛!");
    }

    public static void main(String[] args) {
        Car car1 = new Car("Toyota", "紅色");
        car1.drive(); // 輸出:紅色 的 Toyota 正在行駛!
    }
}

Java 特點:

  • 強型別(變數類型固定)
  • 必須顯式定義類別與方法
  • 所有物件屬性預設是 private(封裝性強)
  • 不支援多重繼承(但可以用 interface 模擬)

🔹 C++:支援 OOP,但不強制

C++ 既可以用 OOP,也可以用傳統程序式方式開發

#include <iostream>
using namespace std;

class Car {
private:
    string brand;
    string color;

public:
    // 建構子
    Car(string b, string c) {
        brand = b;
        color = c;
    }

    void drive() {
        cout << color << " 的 " << brand << " 正在行駛!" << endl;
    }
};

int main() {
    Car car1("Toyota", "紅色");
    car1.drive(); // 輸出:紅色 的 Toyota 正在行駛!
    return 0;
}

C++ 特點:

  • 強型別(類似 Java)
  • 可使用 OOP,也可使用程序式開發
  • 支援多重繼承
  • 手動管理記憶體(new/delete)

🔹 VBA:基本上是程序式,但可以模擬類別

VBA 不是天生的 OOP 語言,但可以用 Class Module 來建立類別。

🔹 VBA 定義類別的方法

  1. VBA 編輯器 中,點選「插入(Insert)」→「類別模組(Class Module)
  2. 重新命名類別(例如:Car
  3. 輸入以下程式碼:
' VBA 類別(Car.cls)
Private pBrand As String
Private pColor As String

' 設定品牌
Public Property Let Brand(value As String)
    pBrand = value
End Property
Public Property Get Brand() As String
    Brand = pBrand
End Property

' 設定顏色
Public Property Let Color(value As String)
    pColor = value
End Property
Public Property Get Color() As String
    Color = pColor
End Property

' 方法:開車
Public Sub Drive()
    MsgBox pColor & " 的 " & pBrand & " 正在行駛!"
End Sub

🔹 VBA 使用類別的方法(標準模組)

Sub TestCar()
    Dim myCar As New Car
    myCar.Brand = "Toyota"
    myCar.Color = "紅色"
    myCar.Drive ' 彈出訊息框:紅色 的 Toyota 正在行駛!
End Sub

VBA 特點:

  • 主要是程序式語言
  • 支援類別(透過 Class Module)
  • 沒有真正的建構子(Constructor)
  • 不支援繼承
  • 主要應用在 Office 自動化(Excel、Word、Access)

🔹 Python、VBA、Java、C++ 類別的相似與不同

語言 支援 OOP? 動態/靜態型別 支援繼承? 支援多重繼承? 主要應用領域
Python ✅ 是 動態型別 ✅ 是 ✅ 是 AI、Web、數據分析
Java ✅ 是 靜態型別 ✅ 是 ❌ 否 企業系統、App
C++ ✅ 是 靜態型別 ✅ 是 ✅ 是 遊戲、系統開發
VBA 🟡 部分支援 動態型別 ❌ 否 ❌ 否 Office 自動化

🔹 總結

✅ Python、Java、C++ 都是 OOP 語言,但 Python 更靈活,Java 更嚴格,C++ 可 OOP 也可程序式。
✅ VBA 不是完全的 OOP,但可以模擬類別,適用於 Office 自動化
學 OOP 的最佳語言Python(簡單易學),Java(規範嚴謹),C++(高效能),VBA(Office 應用)
