When I started learning Python I didn't understand the importance of virtual environments and I installed loads of packages globally. When I updated my Mac it also installed Python 3.8, so now I have that along with 3.7 and its packages.
Largely because it's messy and takes up space, and also to help me have a better handle on how Python is working on my computer, I want to remove the old version and its associated packages and simply have Python 3.8 as it comes with my OS. What can I safely remove without interfering with Python 3.8?
EDIT: Removed previous information that wasn't as relevant to this question.
