[docs] [issue8722] Documentation for __getattr__

Terry J. Reedy <tjreedy@udel.edu> added the comment: Nick, this is about better documenting the behavior of __get(set/del)attr__ in 3.x it relations to AttributeError in a property. I think I understand what it does and think the patch is correct. Could you either review or suggest someone else who better understands core behavior like this? ---------- components: +Interpreter Core nosy: +ncoghlan versions: +Python 3.8 _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue8722> _______________________________________
