Python commands

Using different versions of Python on Windows

If you have several versions of Python installed, you should be able to list them with py --list, which yields something like:

 -V:3.11 *        Python 3.11 (64-bit)
 -V:3.9           Python 3.9 (64-bit)
 -V:2.7           Python 2.7

You can then work with the different versions by writing py -{version_number}. So to install pip for an earlier version of Python, you would write: py -3.9 -m ensurepip --upgrade.

Another alternative is using pyenv: github.com/pyenv/pyenv
