[DamMicSzm]

This pull request is a part of #25193 ( part fix exceptions in python files. )

Problem

Python files need prevent things like syntax errors, typos, bad style, etc... it saves time for reviewing your code. Many python files needed bug fixes.

Changes

Fixed all files where Linter found errors with except and added Linter with temporary exclusion of other errors from flake8 in workflow

Testing

CI will test and maybe some another manual testing
