When you're done working in the virtual environment, you can deactivate it using the following command:
Your terminal prompt will return to its original state.
Creating and activating virtual environments in Python is a crucial step in managing project dependencies. It helps isolate project-specific packages and ensures a clean development environment. By following these steps, you can efficiently set up and work within virtual environments for your Python projects.
