ImportError: No Python documentation found for 'invalid query'.
Use help() to get the interactive help utility.
Use help(str) for help on the str class.
Python 3.10.8 (and most probably any 3.10.*) simply prints this:
No Python documentation found for 'invalid query'.
Use help() to get the interactive help utility.
Use help(str) for help on the str class.
Your environment
- CPython versions tested on: 3.11.0, 3.10.8
- Operating system and architecture: EndeavourOS, kernel: 6.0.1-arch2-1 (64-bit)
Apparently, this is due to commit 8868d48712aee2b490efaf60bed8dfe9fb14d6b7 (thanks to @asottile for finding it).
Is it expected behavior though?

(EDIT) This fix did not catch all cases. See #102541 for
