Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: Documentation Group: Python 2.3 Status: Open Resolution: None Priority: 5 Submitted By: Wilfredo Sanchez (wsanchez) >Assigned to: Raymond Hettinger (rhettinger) Summary: container methods raise KeyError not IndexError Initial Comment: See: http://www.python.org/doc/2.3.5/ref/sequence-types.html, which says, for example, that __getitem__(self, key) should raise an IndexError if key is not in the container. However, built-in dicts raise KeyError instead, and http:// www.python.org/doc/2.3.5/lib/module-exceptions.html#l2h-289 implies that this is the correct behavior. This appears to be incorrect in the current documentation as well as in the 2.3.5 docs. ---------------------------------------------------------------------- >Comment By: Raymond Hettinger (rhettinger) Date: 2005-08-01 16:54 Message: Logged In: YES user_id=80475 Both the behavior and the docs are correct. However, the docs are not especially clear on this point. Will add a clarifying note that KeyError is the appropriate error for mapping types when the key is not found. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1249837&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
