Re: [Python-Dev] Property inheritance in Python
Hi, I apologize if I violate (or am violating) some sacred mailing list rules. Torsten wrote back in 2010 (http://mail.python.org/pipermail/python-dev/2010-April/099672.html) about property inheritance behavior and super(). Specifically, only fget() behavior of properties work with super(), not fset() or fdel(). I apologize if there's some obvious reason this has not been addressed since then, but it seems to be expected behavior and most Pythonic, and confused me greatly when I ran into it recently. Torsten's original thread seems to have gone as if unseen, so I hesitantly bump this topic in the hopes of a resolution. Thanks, Allen

This sort of idea should either be posted on python-ideas to get support or put on the tracker if the proposal is specific enough to write a patch (or both, with a patch making it more likely to happen). -- Terry Jan Reedy
Agreed this could go on the tracker, but I don't see the need for a
Python-Ideas detour. It seems worth fixing (and I vaguely recall there was
some follow-up last time?).

You may be thinking of the abstract property fixes that went in - I'm fairly sure this specific problem report fell through the cracks. Cheers, Nick. -- Sent from my phone, thus the relative brevity :)
