Fix pylint scores on files not being currently checked by pylint

[gizmoguy]

We currently have a bug in src_files.sh that is preventing source files with names that include underscores or numbers from being run with our codechecks (e.g. pylint).

I will be submitting a PR that corrects this issue, however the following files need to be delinted before I can:
