I understand py -0 lists all the versions, and you can select python 2 or python 3 via py -2 or py-3.. but is there a way to use py that selects a 32-bit version of python 3 vs 64-bit?

Any thoughts on using venv, pyvenv, pyenv, virtualenv, virtualenvwrapper, pipenv, etc?
i.e. do they all accomplish the same as changing the paths (PYTHONHOME, PYTHONPATH, PATH, etc ) or is that not the latest preferred/pythonic way?
mkvirtualenv -p python2.6 env
virtualenv --python="/usr/bin/python2.6" "/new_venv_path/"

I'm interested in using the nuitka command-line-tool, but want to force it to build a 32-bit executable!

Great video. I was looking for the 2nd case with the env arrangement. Lol i thought it was funny how you typed "pyton" which is how you said itn then fixed it but then it happed again later in the video but it was a quicker edit lol. Im sure you know, great content

Thank you Bane for explaining how to use other python versions, but it did not work for me. In fact the python paths weren't even in the list of environment variables!!! so I'm still stuck

When I first installed python I never had to add a path variable but now I added a python path variable but that doesn't work. Any Help>

1:50 why are my Python version not installed here?

[joecox]

python shows 3.8.1 but py shows 3.10.4, so I replaced py.exe with 3.81's python.exe

[cyberdemon]

It doesnt work for me, i have v3.11 and v3.10, and it always shows 3.10 even if i delete the 3.10 paths from the environment variables

Why is there a star listed at version 3 in the beginning? Does it stand for default version, dont you uave version 2 as default in the beginning?

[joecox]

tried on Sept not work - I mean change the order no effect, I have 3.8.1 and 3.10.4
