New submission from Carl Friedrich Bolz <cfb...@gmx.de>: The list.index method does not accept None as start and stop, which makes the error message quite confusing:
>>> [1, 2, 3].index(2, None, None) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: slice indices must be integers or None or have an __index__ method I checked this in 3.2.2 and 2.7.2. Seems similar to #12163. ---------- messages: 147000 nosy: Carl.Friedrich.Bolz priority: normal severity: normal status: open title: list.index does not accept None as start or stop type: behavior versions: Python 2.7, Python 3.2 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue13340> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
