I agree with the python-related changes to pre-commit, I'll let @dhdaines review the clang bits since I don't touch that code.

@joanise you might try on a local branch:
pre-commit autoupdate && pre-commit run --all-files
and see if you can fix the black and mypy issues?

Black: since we still want to support Python 3.8, we could bump to 24.8 but not 24.10.
mypy: possibly, when I have some more time to put on this.

Question: is this causing any issue in a project you're working on? I'd like to know where I should put this in my priority list.

black -- Perhaps upgrade to ruff format instead. https://docs.astral.sh/ruff/formatter

Running pre-commit autoupdate is just an occasional good thing to do but it is NOT on the critical path.

Ruff is nice and fast though it isn't always 100% compatible with black.

The C-related changes seem good to me, I think clang-format changed a bit the treatment of preprocessor macros but the result is much more readable.
