We typically use native python version for Linux OSes.
I suppose other python versions like 3.12 will be added separately within activity of aligning GHA / Jenkins workflows.

Agree, the default version of Python must be validated as well.

In that case how should we proceed with testing Python 3.12 in GHA? Back when we had Azure we bumped Python version in all jobs, in addition to usual extension of Jenkins pipelines.

• [PyOV] Enable Python 3.11 #15144
• [PyOV] Enable Python 3.10 on Azure CI #12578

Now the situation has changed, and also I suppose GHA cover more code than Azure did. In that case should we:

• Bump only some GHA jobs to Python 3.12?
• Introduce new jobs or somehow parametrize existing ones to run Python version checks sequentially like Jenkins does?
• Keep Python 3.12 testing in Jenkins, as GHA are already testing a single Python version?

I suggest waiting for "official" GHA work which will align Jenkins and GHA pipelines in terms of Python versions coverage as well.
