> Installing multiple versions of Python? You have got to be kidding.

Why? There's some overhead because it's not like everything has changed between versions, but otherwise it's a very clean way to provide exactly what you need without having to maintain backwards compatibility in future development.

Mind, as long the the Python code you're running _isn't_ using removed or significantly changed function, you can absolutely run code written for Python 3.6 with the 3.8 interpreter, and so on. If I recall correctly, this is _why_ it's uncommon to specify maximum versions in Python packages: unless it is specifically incompatible with a change in a newer version it should generally be assumed to work, and pinning a maximum version would just cause it to fail for no reason.

In your Issue with mod-ui, they specifically say

> mod-ui is not compatible with python3.11, so this wont work.

but your second attempt is still using 3.11 based on your output. It's a shame this isn't better documented since it seems to be known, but that seems like an issue with the project, not Python?
