🎨Pre commit

[mayankpatibandla]

Summary:

Adds pre-commit to run some hooks that must pass before a commit is allowed. Some basic errors regarding whitespace and unused variables have been fixed.

Motivation:

The goal is to enforce a more consistent coding style and fix linting issues. Currently most errors have been disabled, but we will need to enable some of them later to comply to a chosen standard.

Test Plan:

• To set up pre-commit, run pip install pre-commit if you don't already have it, and then run pre-commit install in the project directory. Pre-commit hooks should now run automatically every time a new commit is made.
• Make sure that pre-commit run --all-files passes for all files in the project.

From the diff I can't see the difference between this and #301. What was the purpose of this PR again?

[mayankpatibandla]

#300 got merged into #301 so that #301 could be tested. You originally said that you wanted me to put them in two separate PRs. Do you still want that or can we get rid of #300?

[ayushuk]

Oh right. Yeah I think we can close #300 since I think I was trying to be safe before doing a release. Since we are merging this after a release we should be able to merge everything together since #301 has everything. Feel free to close this PR and lets merge only #301.

Closed because this PR got merged into #301
