Most changes to Python require a NEWS entry.

Please add it using the blurb_it web app or the blurb command-line tool.

Thanks for your interest in improving CPython!

Unfortunately, cosmetic changes are usually not accepted for the CPython repo. We have a large number of open bug reports, and prefer to spend our time fixing those.

@AlexWaygood thanks for your comment, I wanted to do a separated pull-request from the modification I intend to do on bug gh-42811
Then I will do this cosmetic change embedded with this other PR

@chouetz, we'd prefer it if you didn't do the cosmetic change at all, if that's okay :) including the change as part of a substantive PR will create a confusing diff and distract from the PR's main purpose

@AlexWaygood ok then we don't "fix" this kind of stuff, or only when noticed within a development that targets a precise block of code? Would it be ok if it's on a specific commit within a PR? Especially here because it's really trivial (I completely understand we don't want to bring confusion during a code review)
Sorry to ask such questions, just trying to do things right
Thanks in advance

Sorry to ask such questions, just trying to do things right

Of course, no worries!

Yeah, in general, we don't "fix" this kind of stuff:

• Lots of the CPython codebase is really old and predates these kinds of style guides being written. If we encouraged PRs like this, there's unfortunately a risk that we'd get deluged with PRs "cleaning up" the CPython codebase, which isn't something we really want.
• People have different opinions about what constitutes "good style", so encouraging PRs like this leads to annoying back-and-forths (E.g. I don't find the proposed change here significantly more readable, personally 🙂)
• Cosmetic PRs lead to code churn and confusing git blame.

Every repo has their own policy on PRs like this; some are much more receptive than others; this is just the stance CPython has chosen to take here.
