From f6aa86e33ba5b29ff9bd442e80e196746b5d2424 Mon Sep 17 00:00:00 2001 From: Brett Cannon Date: Wed, 20 Sep 2006 18:43:13 +0000 Subject: Allow exceptions to be directly sliced again (e.g., ``BaseException(1,2,3)[0:2]``). Discovered in Python 2.5.0 by Thomas Heller and reported to python-dev. This should be backported to 2.5 . --- Misc/NEWS | 2 ++ Objects/exceptions.c | 9 ++++++++- 2 files changed, 10 insertions(+), 1 deletion(-) diff --git a/Misc/NEWS b/Misc/NEWS index 911f721..c5cc2af 100644 --- a/Misc/NEWS +++ b/Misc/NEWS @@ -12,6 +12,8 @@ What's New in Python 2.6 alpha 1?
