This can be done by replacing the star wildcard the join(dir, '*') with a
filename or filename glob pattern.

magic-wormhole 0.19.0
-BEGIN PGP SIGNED MESSAGE- Hash: SHA512 Greetings, Wizards have foretold that May 28, 2025 marks the release of Magic Wormhole version 0.19.0. Magic Wormhole is a Python library and CLI tool to securely get arbitrary data from one computer to another using short, one- time, human- pronounceable codes and end-to-end encryption. The library allows use of the lower-level protocol for things besides file-transfer. In this release are the following changes since 0.18.2: * Add a "status" feedback API for Dilation (#591, @meejah) * use new Status API to notify a sending user when a code is consumed (#575, @shapr + @meejah) * add support for Ping/Pong timeouts in Dilation, improving re-connection speed (#590 @meejah) * documentation improvements (#614, #615 @shapr + @meejah) * improve Dilation version negotiation (#606, #611 @shapr + @meejah) * convert test-suite to pytest (#603, #610 @shapr + @meejah) * resize progress bar properly (#622 @shapr) * Drop support for Python 3.9, upgrade github-actions (#596 @meejah) * add a contribution guide (#597 @meejah) * INCOMPAT: "sdist" files move to an underscore, so the source-package name is now "magic_wormhole-0.19.0.tar.gz" (the wheel files always had an underscore). This is because setuptools v69.3.0 in 2024 implemented PEP 625 from 2020. You can find the release on PyPI: https://pypi.org/project/magic-wormhole/ More information can be found: https://magic-wormhole.readthedocs.io/en/latest/welcome.html https://github.com/magic-wormhole/magic-wormhole thanks, meejah -BEGIN PGP SIGNATURE- iQFFBAEBCgAvFiEEnVor1WiOy4id680/wmAoAxKAaacFAmg33IURHG1lZWphaEBt ZWVqYWguY2EACgkQwmAoAxKAaaeUtQgAqtR8OfDXclj6YoeLc/Q594uI/ds0fvzA OCzetbLzUZF0fkFIfyFCHPLvNBD+TYXLYfo0E/pbRPklGxrMcntrgmYFERet2ZA3 p7oUxc79ylEm7Pp9Z5p/1YhYsz8PtrsZd7QPlip9OdBnKC9JAiZWv/F+8BHnNtvg OTfzK8to2wnPWR/XizFvk4X54p5PkczIo6nWOvscZ3FbtJErqZVTgSrfL9jNFFed V/GLHU/V1HhkY7zITvwL8+q1reJwymkf2oznJ6/ezgTRYyR3ISwhf5jOHhTlwRl5 SgNwNwlQU2pX4uXWsdTyTcWYMctlHKIcnYxUtiNHpHVgQ+TOTOnxhw== =wEqZ -END PGP SIGNATURE- -- https://mail.python.org/mailman3//lists/python-list.python.org

I sent a test message and it sent a response saying my message was in a queue waiting for the moderator. But since that's me and it won't let me in, I can't approve anything, So I assume there will be a bunch of stuff just sitting in a queue waiting for a non-existent moderator. I guess this proves the list is still there in some form! Back to the postmaster to see how I get this fixed... I do notice we seem to have moved to Mailman3 as a server, perhaps it has something to do with the migration? It would have been nice to be told though. Interesting - list transitions from 2->3 are supposed to be quite difficult, it's really a different piece of software that happens to still be called Mailman, not a simple version transition. When I've asked about other lists (hosted elsewhere on a "free to open source projects" basis), been told pretty much "ain't gonna happen". I'm surprised python.org would have made such a move without letting anyone know, though I'm not surprised there was some motivation since Mailman 2 is pinned forever to the slightly out-of-date (sic) Python 2 -- https://mail.python.org/mailman3//lists/python-list.python.org

Re: Python tutor mailing list?
Being a user of that list i've also noticed that only recently. hope that this list is good enough to take on all python questions. Are there any other alternative lists?
