Pylint?

[davet2001]

@padelt How do you feel about pylint?

Could be a code improvement? Probably a dedicated PR with no functional change, just formatting/renaming. All tests should pass before and after.

To give an idea, these are the current errors:

[padelt]

Not a big fan of refactoring working code only to conform to things like Too many branches or Variable name "th" doesn't conform to snake_case naming style (invalid-name) in general.

But if you as a human with common sense judgement would want to comb through those hints to improve the code - please feel free to do that!
