  11. Install Python packages: In a virtual environment, you can install the necessary Python packages, for example, installing the requests package.
  12. install requests using pip
  13. Exit the virtual environment: After completing your work, use the following command to exit the virtual environment:
  14. turn off

By following the steps above, you can configure a Python environment on a Linux system and independently manage the Python versions and packages required for projects.
