Hmm, this was an intentional style choice. I find it easier to read with the whitespace. I'm assuming this is a new addition to flake8. Can you point me to the warning and/or the documentation? We may want to disable this new rule and/or enforce the opposite behavior.

They show up as E201 and E202:

flake8: install_deps> python -I -m pip install flake8

They come from pycodestyle. Strangely, only ( and ) are mentioned in the docs, not { and }: https://pycodestyle.pycqa.org/en/latest/intro.html#error-codes. Can't find anything relevant in their changelog.

Happy to revert and ignore these rules instead 🙂

pycodestyle's docs are not up to date... Latest version is 2.12.1, changelog only shows 2.11.1: https://pycodestyle.pycqa.org/en/latest/developer.html#id2. This was reported here: PyCQA/pycodestyle#1271.

OK so the errors don't show up in CI because it uses Python 3.11, and locally I used 3.13. They only show up on 3.12+ apparently.
