So I was using pythonV3 for the past few months. But then I somehow messed up my Python installation.
So I decided to start from scratch: I uninstalled all Python from my computer and reinstalled Python3.8.1. Or at least I thought I did.
When I try to check which version of Python I have by using the python --version or python3 --version commands, I get no message at all. No error message and no confirmation message.
