Thanks for PR.
Please fix notes.
I suggest installing codecov browser extension: https://docs.codecov.io/v4.3.6/docs/browser-extension
You'll see uncovered red lines just in Files changed tab on gihub.

Please not make a new fileno local variable but reuse fd in the rest of function -- like selectors._fileobj_to_fd does.

fd is used later in this function to format a better error message. This is not a copy/paste of selectors._fileobj_to_fd.

Please avoid backticks -- without them the comment is still pretty clean.

Removed, but this is a very personal preference -- for me it was easier to read that comment with backticks/quotes.

@1st1 I hate any complex markup in comments, selectors._fileobj_to_fd without backticks is still pretty readable and understandable.
This is just my opinion.
But if you want to keep them -- I can live with it. Very minor thing about a taste.

Added a functional test for this.

This won't be covered as it's test_utils' test loop. There's no point in covering it.

Maybe let's add # pragma: no cover comment for except clause?
It increases formal coverage level at least (:

Original PR python/asyncio#420 missed the fact that
loop.add_readerandloop.add_writeraccept file-like objects in addition to int FDs.
