        else:
            self.copy_constructor(orig)
    def non_copy_constructor(self):
        # do the non-copy constructor stuff
    def copy_constructor(self, orig):
        # do the copy constructor

a=Foo()  # this will call the non-copy constructor
b=Foo(a) # this will call the copy constructor
