what I expected to happen

Only the Python 3.12 run shows this error, while Python 3.10 and Python 3.11 succeed successfully.
Expecting to also pass for Python 3.12

Please re-read the issue template. Flake8 does not implement any checks.

For anybody else who lands here: this issue occurs in pycodestyle 2.10.0 but is fixed by upgrading to pycodestyle 2.11.0.

(Which was the first version of pycodestyle to support Python 3.12.)
