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: None >Status: Closed >Resolution: Invalid Priority: 5 Private: No Submitted By: emlyn (emlyncorrin) Assigned to: Nobody/Anonymous (nobody) Summary: Documentation error (section 3.4.1) Initial Comment: In the documentation section 3.4.1 Basic customization (url: http://docs.python.org/ref/customization.html) it states: There are no reflected (swapped-argument) versions of these methods (to be used when the left argument does not support the operation but the right argument does); rather, __lt__() and __gt__() are each other's reflection, __le__() and __ge__() are each other's reflection, and __eq__() and __ne__() are their own reflection. Surely that should be __lt__() and __ge__() are each other's reflection, and __le__() and __gt__(). I assume this is just a typo, but I haven't checked that Python itself gets it right. ---------------------------------------------------------------------- >Comment By: Žiga Seilnacht (zseil) Date: 2007-03-17 16:40 Message: Logged In: YES user_id=1326842 Originator: NO No, the documentation is correct (as well as Python's behaviour). For example, you have a left_five and right_five, which are int like objects with value 5, and left_five is missing a __lt__ method. If you do a left_five < right_five comparison, you want right_five's __gt__ method called, because right_five's __ge__ method would return True, since their values are equal. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1682729&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
