Yes, they are all different. The first one calls B's immediate base class but packs all of the arguments together into a single tuple. Probably not what you meant. The second one passes B's positional arguments to its immediate base class without messing them up but uses a deprecated function to do it. You should use "A.__init__(self, *args)" instead unless you are concerned about multiple inheritance. The third one skips over the __init__ method in the immediate base class and calls the __init__ method in whatever class follows A in the MRO instead. Probably not what you meant either. -- http://mail.python.org/mailman/listinfo/python-list
