I am probably confused about immutable types. But for now my questions boil down to these two:
- what does ``tuple.__init__`` do? - what is the signature of ``tuple.__init__``? These questions are stimulated by http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/303439 Looking at that, what fails if I leave out the following line? :: tuple.__init__(self) For exaple, if I try:: class Test1(tuple): def __init__(self,seq): pass I seem to get a perfectly usable tuple. What initialization is missing? Next, the signature question. I'm guessing the signature is something like tuple.__init__(self, *args, **kwargs) with nothing done with anything but self. As a trivial illustrative example:: class Test2(tuple): def __init__(self,seq): tuple.__init__(self, "foo", "bar") seems to cause no objections. One last question: where should I have looked to answer these questions? Thanks, Alan Isaac -- http://mail.python.org/mailman/listinfo/python-list
