Using mutable default arguments in functions is dangerous: https://docs.python-guide.org/writing/gotchas/#mutable-default-arguments

@frebib makes a valid point. The article they referenced demonstrates how to better handle this scenario. The Lint Failures are related to this as well.

@frebib Will update the code with immutable default.
@twangboy I'll need to figure out how to add tests for this, and there might be needed some extra cycles of tests correction as well.
Thank you!

@twangboy do I need reformat code as pipeline shows? Also, do I need to rebase changes periodically, or they will be just merged on top, if no conflicts appears?

Yeah, you need to fix pre-commit/lint failures. I just did that
