From c1f6e8cbc1d60c5fe00121c67bfc581301e7ce50 Mon Sep 17 00:00:00 2001 From: Guido van Rossum Date: Wed, 16 Apr 2003 21:13:23 +0000 Subject: - The repr() of a weakref object now shows the __name__ attribute of the referenced object, if it has one. Also use %p to format pointers consistently, and use in proxy_repr(), to match the type name. --- Misc/NEWS | 3 +++ Objects/weakrefobject.c | 21 +++++++++++++++------ 2 files changed, 18 insertions(+), 6 deletions(-) diff --git a/Misc/NEWS b/Misc/NEWS index 1e3800b..5cc7ce8 100644 --- a/Misc/NEWS +++ b/Misc/NEWS @@ -12,6 +12,9 @@ What's New in Python 2.3 beta 1?
