To set up Black as your default Python formatter in VS Code:

1. Install the required extensions:

   • Install the Python extension by Microsoft.

   • Install the Black Formatter extension from the marketplace.

2. Set Black as the default formatter:

   • Open your settings.json file via Preferences: Open User Settings (JSON).

   • Add the following configuration to set Black as the default formatter for Python files:

     "[python]": {
       "editor.defaultFormatter": "ms-python.black-formatter"
     }

3. Enable auto-formatting on save:

   • Add this line to your settings.json:

     "[python]": {
       "editor.formatOnSave": true
     }

4. Optional: Customize Black settings:

   • To change line length (default is 88), add:

     "black-formatter.args": ["--line-length", "120"]

⚠️ Troubleshooting: If formatting doesn’t work, ensure Prettier is not overriding the Python formatter. Check your settings for "editor.defaultFormatter" and remove any conflicting configurations. Also, confirm Black is installed in your Python environment (pip install black).
