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: Python Library Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: David Benbennick (dbenbenn) Assigned to: Nobody/Anonymous (nobody) Summary: A subclass of set doesn't always have __init__ called. Initial Comment: Consider the following code: >>> class foo(set): ... def __init__(self, iter): ... print "foo.__init__" ... set.__init__(self, iter) ... >>> x = foo([1,2]) foo.__init__ >>> y = foo([2,3]) foo.__init__ >>> x & y foo([2]) As you can see, the foo.__and__ method creates a new foo object without calling foo.__init__. The problem is in Objects/setobject.c:make_new_set(). ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1721812&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
