python and py report different versions

[lordvold]

I've installed Python 3.7.5 on a Windows 10 machine. No other version of Python was ever installed on that machine that I know of (and no-one else uses it). On the Windows Command Prompt, when I query the version with python -V I get Python 2.4.5, while when I use py -V I get Python 3.7.5.

I'd like to know why because I know that one can tie oneself in knots when packages (e.g. pip) detect the 'wrong' version.

What I have in my system's PATH is %homepath%\AppData\Local\Programs\Python\Python37\, and the same with Scripts\ appended.

Thanks
