Adopting pre-commit and Auto Formatting #890
Description
We are adopting auto-formatting, including black and isort on all files. cf #889
From the Django Enhancement Proposal to use Black:
Reformatting will also be disruptive for open pull requests. One way to update them is to run Black on modified files, keep a copy aside, start a new branch from "main", move the modified files back into place, and commit the result.
Contributors will be asked to install pre-commit locally. We also have the option to use @meeseeksdev please run pre-commit on PRs if needed.
