and what python version do not work.

This largely depends onwhether the core python binding work. Unless deltabot uses some newer Python feature, which is unlikely as it has not been updated for a while. Core currently supports versions from 3.7 up to 3.12: https://pypi.org/project/deltachat/#files

Note that this is about documentation and still relevant for end users and bot devs. maybe add a check in the start of the core bindings that print an error if you use the wrong version.

If there are no wheels for your python version, pip will not even install anything, there is no way to check anything in runtime.

Back then it was some syntax error because the python version i was using was too new if I remember it correctly. Like 3.10 while it(deltabot or python bindings) was still python 3.8, but I don't remember the details unfortunately.
