Python 3.12.0 raises incorrect E231 in fstring

[eXhumer]

I have made a 3.11.6 & 3.12.0 venv's and installed flake8 on both with pip install --upgrade flake8. I then added a fstring with : in a script, VSCode incorrectly reports E231 (missing whitespace after ':') in the 3.12.0 environment, while no such error is reported on 3.11.6.

This is a vscode-flake8 and not a flake8 issue as there is no E231 reported by flake8 command.

@eXhumer Can you share the version of flake8 you have in each of the environments? Also, can you share the logs from Output > flake8.

In the logs it should show which version of flake8 is loaded and is being used. The extension itself does not generate any error codes. The only issue that I think here is that the extension is using the bundled version of flake8.

Please be careful when using pip command directly, it may not install it where you expect it to: https://snarky.ca/why-you-should-use-python-m-pip/?web=1

I have flake8==6.1.0 installed in both environments.

@eXhumer From the logs it is picking up flake8==5.0.4. Set flake8.importStrategy to fromEnvironment to use flake8 from your environment.

That has fixed the issue for me, thanks. I hunted down the specific bug and this appears to be the problem. A permanent fix seems to be to upgrade bundled flake8 to 6.1.0 where pycodestyle gets updated to 2.11.0, which includes the above mentioned PR.

Should I close this issue or keep it open till the bundled flake8 is updated?

Close it. For your needs you should have it set to fromEnvironment. We will be makeing a release soon-ish with 3.12 package updates.
