Pylint alerts corrections as part of an intervention experiment

[evidencebp]

Pylint alerts are correlated with tendency to bugs and harder maintenance.
I'd like to conduct a software engineering experiment regarding the benefit of Pylint alerts removal.
The experiment is described here.

In the experiments, Pylint is used with some specific alerts, files are selected for intervention and control.
After the interventions are done, one can wait and examine the results.

Your repository is expected to benefit from the interventions.
I'm asking for your approval for conducting an intervention in your repository.

See examples of interventions in stanford-oval/storm, gabfl/vault, and coreruleset/coreruleset.

You can see the planed interventions

Since the plan includes only 3 internevtions, I'll submit a PR fixing them.
I'll be happy to know what do you think of the PR and if you would like to modify it or merge it, @akrherz

I see that the CI/CD alerts on commented out code.
This comment was in the original file, its position was changed due to method extraction.
@akrherz , please tell me if you want me to remove it.
