I have a subclass of int where I want all the standard arithmetic operators to return my subclass, but with no other differences:
class MyInt(int): def __add__(self, other): return self.__class__(super(MyInt, self).__add__(other)) # and so on for __mul__, __sub__, etc. My quick-and-dirty count of the __magic__ methods that need to be over- ridden comes to about 30. That's a fair chunk of unexciting boilerplate. Is there a trick or Pythonic idiom to make arithmetic operations on a class return the same type, without having to manually specify each method? I'm using Python 2.5, so anything related to ABCs are not an option. Does anyone have any suggestions? -- Steven -- http://mail.python.org/mailman/listinfo/python-list
