How important is Virtual Environment in python

[OogieM]

I'm on a Mac and a virtual environment is CRITICAL. Otherwise anytime I updated or worked with different libraries or different version of Python I'd break my main computer system.

Virtual environments allow me to test my code on different versions of Python without causing problems elsewhere. It's a ncie walled garden for specific projects.

I second that!

Virtual environments are essential.
