looking fo documentation for module files

[Skaperen]

how can i put the local path in the front of sys.path?

Python 3.5 can say is dead💀 as many modules/libraries dos not support for it anymore.

isn't it supposed to be that code written for Python 3.X should work in Python 3.Y where X < Y ? could my code written for Python 3.6 fail in Python 3.8 or Python 3.10 or even Python 3.11 ? i thought such failures were to be limited to major version changes, e.g. code for Python 2.7 could fail in Python 3.X for each X.
