Debugging Your Code
Debugging is crucial for any developer. To debug your Python code within VS Code, follow these steps:
1. Setting Breakpoints
Click on the margin next to a line number in your Python file to set a breakpoint. This will make VS Code pause the execution at that line.
2. Start Debugging
Press F5 to start debugging. You can step through the code, inspect variables, and see the call stack in the Debug view.
Customizing Your Python Environment in VS Code
VS Code allows you to create a personalized development environment by customizing settings and configurations.
Using Virtual Environments
Using virtual environments is crucial when managing dependencies for different projects. Here’s how to set one up:
- Open a terminal in VS Code.
- Navigate to your project directory.
- Run the command: `python -m venv venv` to create a virtual environment.
- Activate the virtual environment:
- On Windows: `.\venv\Scripts\activate`
- On macOS/Linux: `source venv/bin/activate`
Once your virtual environment is activated, you can install packages using pip without affecting system-wide installations.
Configuring Settings and Shortcuts
To access and modify your settings:
- Go to File > Preferences > Settings.
- From here, you can search for specific settings related to Python, like formatting, linting, or enabling/disabling IntelliSense features.
You can also customize keyboard shortcuts by going to File > Preferences > Keyboard Shortcuts.
