In the maybe_freelist_push function, PyTupleObjects with an ob_size of 20 are being stored in the free_list for potential reuse. However, in the maybe_freelist_pop function, these objects aren't actually being reused.

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.

Looks good! Tuples with size 20 are probably not very common, but since the freelist is allocated for them let's use it when possible.

@eendebakpt Hi, When will this submission be merged? Is there anything else I need to do?

@eendebakpt Hi, When will this submission be merged? Is there anything else I need to do?

One of the CI tests is still failing (formatting of the news entry). If that is fixed all CI checks should be green.

The PR needs to be reviewed and approved by a core developer in order to be merged. It can take some time before this happens though, as there are many issues and PRs requiring attention.

A Python core developer has requested some changes be made to your pull request before we can consider merging it. If you could please address their requests along with any other requests in other reviews from core developers that would be appreciated.

Once you have made the requested changes, please leave a comment on this pull request containing the phrase I have made the requested changes; please review again. I will then notify any core developers who have left a review that you're ready for them to take another look at this pull request.

@corona10 @eendebakpt Sorry，I have made the requested changes，but I don't understand why there are still three checks failing. Just to mention, this is my first time contributing code to CPython, so I'm not very clear on some of the details.

@satori1995 Failing docs test could be due do the formatting in the news entry, although I am not sure as the error message does not show any line our text of the news entry in this PR. Could you rebase your branch onto latest dev? (in github there is a button "Update branch" for this). Maybe that resolves the failing test.

@satori1995 The failing checks we can resolve, your part of the PR looks good. Could you sync your PR the the main branch? (the Update branch button)
