Hi!

While rebuilding the python related packages against the Python 3.15rc2
version we found that afew fails to build from source:
https://debusine.debian.net/debian/r-python-python3.15/artifact/4855991/

 From the log, the error seems to be:
==================================== ERRORS

This is caused by glob.glob1 getting removed. See
https://docs.python.org/3.15/whatsnew/3.15.html#glob:

Removed the undocumented glob.glob0() and glob.glob1() functions, which
have been deprecated since Python 3.13. Use glob.glob() and pass a
directory to its root_dir argument instead. (Contributed by Barney Gale
in gh-137466.)

Setting the severity to important for now. Once Python 3.15 is released
and later added to python3-defaults, this bug will become release
critical.
