From 9b3be7f5d9084dce06d6dec3657e649f9769ecc8 Mon Sep 17 00:00:00 2001 From: Barry Warsaw Date: Tue, 14 Aug 2001 18:35:02 +0000 Subject: Document 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).
