From d67a9c0a13cc4458e3d71ccff182d82d0632b209 Mon Sep 17 00:00:00 2001 From: Barry Warsaw Date: Tue, 14 Aug 2001 18:22:24 +0000 Subject: Describe the new semantics for setting and deleting a function's __dict__ attribute. Deleting it, or setting it to a non-dictionary result in a TypeError. Note that getting it the first time magically initializes it to an empty dict so that func.__dict__ will always appear to be a dictionary (never None).
