Since the original poster is invoking python.exe directly, probably as
per the instructions in the book he's following, I fear having two
versions of python installed will just lead to confusion.  In his case,
I think it's best to just have Python 3.8 installed.  Although
pgzrun.exe will almost certainly execute the correct version of Python,
so probably wouldn't matter either way.
