如何在 VS Code 中設定工作目錄以實現高效 Python 偵錯？

Setting the Working Directory for Python Debugging in VS Code

For seamless debugging in VS Code, specifying the working directory is crucial. Here's how to achieve it:

Dynamic Working Directory via launch.json

Utilize the "cwd" option in launch.json to set the working directory to the location of the open Python file. This dynamic approach ensures that the correct directory is always used:

<code class="json">"cwd": "${fileDirname}"</code>

Note: Ensure capitalization and correct spelling of "fileDirname."

Additional Configuration (Optional)

Depending on your debugging method, you may need to include the "purpose" option:

<code class="json">"purpose": ["debug-in-terminal"]</code>

This option is necessary if using the play button or "Run and Debug" sidebar option.

Example Launch.json Configuration

For debugging with the Python: Current File (Integrated Terminal) option, your launch.json might resemble:

<code class="json">{
    ...
    "configurations": [
    {
            "name": "Python: Current File (Integrated Terminal)",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal",
            "cwd": "${fileDirname}",
            "purpose": ["debug-in-terminal"]
    },
    ...
}</code>

Creating a launch.json File

If you don't have a launch.json file, follow these steps:

• Open the project folder in VS Code.
• Click the "Configure" gear icon in the Debug view top bar.
• Click "Create a launch.json file."
• Select Python as the debugging language.

Alternative Method

• Click the Debug button on the navigation panel.
• Select "Create..." when prompted to create a launch.json file.
• Choose Python as the debugging language.
