I've got a solution for https://py.checkio.org/en/mission/bird-language/ It works locally in PyCharm using python 3.13 (the same version as the checkio server).

When I try to check the solution using the checkio_client, I see this output:

./bird_language.py --check Example: hello The mission is done! Click 'Check Solution' to earn rewards!

Start checking...

['err', "ImportError: cannot import name 'T' from 're' (/usr/local/lib/python3.13/re/init.py)\n <module>, 20", 'req'] !! Failed !!

When I try to check the solution online, I see this output:

ImportError: cannot import name 'T' from 're' (/usr/local/lib/python3.13/re/init.py) <module>, 1

The line in my solution that is causing the error on checkio.org is the first line of code:

import re

Seems like a bug on the server. It's annoying that I run into this bug within 24 hours of signing up. It doesn't make sense for me to be finding bugs this quickly on one of the easiest missions available.

Please fix.
