> I recommend using two tools together: Black and isort.
Black formats things differently depending on the version. So a project with 2 developers, one running arch and one running ubuntu, will get formatted back and forth.
isort's completely random… For example the latest version I tried decided to alphabetically sort all the imports, regardless if they are part of standard library or 3rd party. This is a big change of behaviour from what it was doing before.
All those big changes introduce commits that make git bisect generally slower. Which might be awful if you also have some C code to recompile at every step of bisecting.
Two developers on the same python project should also use the same version... with poetry it is straightforward to keep track of dev dependencies. Reorder python imports is an alternative for isort: https://github.com/asottile/reorder_python_imports
