what is an exit venv command?

If you work with Python, you've probably heard of the term "virtual environment" before. A virtual environment is simply an independent environment set up in your computer for specific projects. Each virtual environment will have its own set of installed packages and libraries that you can use exclusively for that project. It's important to note that these packages will only exist inside the virtual environment, and not in the global application directory – this helps maintain system integrity and dependency management.

The exit venv command is used to explicitly "exit" a specific virtual environment on a computer. When executing this command, all changes made within that virtual environment are discarded, and the user is returned to their global application directory (referred to as a global Python installation).

For example, if one were working on a project in their virtual environment with multiple installed modules required for the project codebase, and then decided to leave the project completely (not just stop working on it temporarily) they would need execute the 'exit venv' command. This would cause any changes made within the virtual environment during the duration of that projects life-cycle to be discarded – meaning if you attempted to access that specific projects modules anywhere else within outside of its original virtual environment, they wouldn't exist anymore; this command creates an isolated instance for your project which no longer persists once you leave it by using this command.

Letting go of any changes made in previous versions of your project can be difficult – fortunately there are always ways around this with proper storing practices; always make sure to document any custom installations done within the scope of your project so you never lose track of them!
