Pylint alerts corrections as part of intervention experiment

Is your feature request related to a problem? Please describe. There are two wildcard import in examples\issues\issue37.py

In general, wildcard imports should be avoided since the imported object are hidden. Actually, a working code might break due to adding object to the imported file, that will conflict with others.

Describe the solution you'd like Replace the wildcard imports with the specific objects to import.

Additional context

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.

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.

In this project the intervention is very simple, fixing two wildcard import alerts. Therefore I created the PR already.

@pmbarrett314 , If you are OK with the PR I'll be very happy if you will merge it so I'll be able to observe the outcome of the fix.
