Fix tests

[peterdudfield]

The CI tests are currently failing, it would be great to get these working again

Hey there, i see that the last failing pipeline shows that ruff is failing, and i see there are tons of errors
see here
Is the pipeline expected to fail when not meeting this requirements, should the "real issue" be fix formatting or maybe loose the rules a little bit?

[peterdudfield]

yea, perhaps it is to fix the formatting. What do you think should be done? Fix formatting or loosen the rules?

[jramosss]

First of all maybe change the name of the issue to fix formatting issues.
Then, definitely loosen the rules, unless the philosophy of the repo is to use docstring (maybe in core/big functions helps, but i don't think every function should have a docstring)
I created a new one, see #67
