Looks good @hananell! I ran black linter for you — you can also do it locally by running make lint (to view issues) and make format (to fix issues) in the future.

The linters are picking up on a couple of issues (looks like the ruff linter), again, you can check locally with make lint or check out the failing action above. If we can get those fixed we can merge, thanks!
