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. -- https://mail.python.org/mailman/listinfo/python-list
