I take the point of the other responders that it is not a normal thing to 
do, but I had a few long but rarely used methods which I wanted to move out 
of the main file just to keep the main file tidier. I came up with this 
solution, and it seems to work.

In test2.py -

    def long_method_1():
        pass

    def long_method2():
        pass

In test.py -

    import test2

    class Foo:
        long_method_1 = test2.long_method_1
        long_method_2 = test2.long_method_2

Then in Foo I can refer to self.long_method_1().
