Most changes to Python require a NEWS entry. Add one using the blurb_it web app or the blurb command-line tool.

If this change has little impact on Python users, wait for a maintainer to apply the skip news label instead.

Hi! Thanks a lot for your work (this is the first commit, yey!)
But, this is consider a stylistic-only change. We try to keep the amount of such changes as low as possible in CPython's codebase. Because they can introduce bugs, create possible merge and backport conflicts, and ruin git history.

All such changes are merged based on module maintainer's decision :)

However, thanks again for noticing this!

I'm going to decline this one. It is a minor stylistic edit. In general we defer to the original author on matters of style. Also, in this particular case I think the edit makes the code harder to read. It doesn't look nice.
