If you do that and it results in a working system, you can then patch mailman/utilities/i18n.py as follows
Thank you. This works, and I can successfully import a first list configuration.
However there are other incompatibilities between the released Mailman versions and Python 3.13.
Hmm https://docs.mailman3.org/en/latest/install/virtualenv.html states "3.13 is recommended as it is the latest version of Python with which Mailman is tested."
At the moment, until updated packages are released, in a Python 3.13 environment it is best to install all of mailman, django-mailman3, postorius, hyperkitty and mailman-web from the heads of the gitlab branches.
I would love to see a command line for that. When I go to the gitlab page, https://gitlab.com/mailman/, I see a bunch of project that don't immediately correspond to pip package names.
I am sure this would help other folks using 3.13 as they have been recommended to do.
Thanks and cheers!
