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().
