Spent over an hour trying to get matplotlib to work

So it seems like every line you wanted me to type worked fine apart from the last one?

It's not one _ but two __version__
So it work as you don't get error on import.

This is what I get when I try to do a basic thing in matplotlib:

As i mention so most you configure editors in this case Sublime to use Python 3.8.
Add this in code then you see what version you run,and Path it use.

import sys

print(sys.version)
print(sys.executable)

VS Code is an other option that's a very good editor for Python and free.
VS Code from start
