Python has an extensive ecosystem of libraries and tools, and managing these packages is essential for efficient development. VS Code makes it easy to work with these libraries using pip.
1. Installing Packages
To install packages using pip within the integrated terminal:
pip install package_name
Replace package_name with the name of the package you wish to install.
2. Creating a Virtual Environment
Utilizing virtual environments helps manage dependencies for different projects without conflicts:
- Open the integrated terminal in VS Code.
- Navigate to your project directory.
- Run the command `python -m venv env` to create a virtual environment named `env`.
- Activate the environment:
- Windows:
.\env\Scripts\activate
- macOS/Linux:
source env/bin/activate
- Install packages as usual using pip within the activated environment.
This structure allows you to keep project dependencies isolated, making your coding experience smoother.
Customization and Themes
Visual Studio Code offers extensive customization options, enabling you to tailor the environment to your personal preferences and style.
1. Changing Themes
To change the editor’s theme:
- Go to the menu bar and select File > Preferences > Color Theme.
