drop python<=3.7 support

[kloczek]

According to https://endoflife.date/python python 3.7 has been EOSed almost year ago. Filer all code over pyup[grade --py38-plus.

Unfortunately openSUSE Leap 15.4 and Leap 15.5 still have Python 3.6:

https://news.opensuse.org/2023/06/06/leap-modern-python-stack/

I introduced this to make it work on these openSUSE versions:

if sys.version_info >= (3, 8):
    from typing import Literal
else:
    from typing_extensions import Literal
from typing import Literal

Without that, one gets

ImportError: cannot import name 'Literal'

on openSUSE Leap 15.4 and Leap 15.5.

Your second patch "filter all code over ruff" looks completely fine.

Without that, one gets

ImportError: cannot import name 'Literal'

on openSUSE Leap 15.4 and Leap 15.5.

typing is standard module which have been evolving since python 3..5.

Which one version of the python is in that distro? 🤔

From https://peps.python.org/pep-0586/ So I'm assuming that this SuSE version is using one od the oleder versions which already is EOSed 🤔

openSUSE Leap 15.5 and 15.4 have Python 3.6 as default. There are optional addons for newer Python versions, but they lack some modules.

typing is available since python 3.5, but Literal needs python >= 3.8.

I pushed that one to main already.

Yes, but not right now because I think I stlll need to keep Python 3.6 compatibility because of openSUSE Leap 15.5.

[mike-fabian]

I have pushed all changes not to main except for the change related to from typing import Literal. That keeps Python 3.6 compatibility for the moment.
