This is not grammatically correct: a sentence should start with a capital letter and contain a verb.

Thank you, how about
"By default, it holds entries to handle the standard kinds of modules (.py files, extension modules...)."

Technically there aren't different kinds of modules, just different ways of storing code. I have suggested a tweak to the wording.

No, as that's too easy of a thing to forget to update. Plus there's no guarantee that every interpreter will set up sys.meta_path the same.

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.

I don't think the docs should get too specific as interpreters can choose what to put into sys.meta_path.

Changes were requested by a core dev over two years ago, but have not been made. I am therefore closing this PR.

@Windsooon, if you're still interested in working on this, feel free to open a new PR. Alternatively, ping me, and I'll happily reopen this PR. Thanks! 🙂
