Fix errors from github actions

[cheezyrock]

A number of files have failed linter Github actions. Quite a few of them are small things that should be fixed.

1. Missing Function Docstring
2. unused variables and undefined variabled
3. redefining variables in different scopes.
4. More (See failed actions in GitHub for more information, use judgment on what should be fixed or ask team lead)

These should be addressed and should all be minor changes. This will be an ongoing task until all issues are addressed and the GitHub action passes.
