When you ask a question, it help people answer if they know what you 
have already tried and failed with ;-)

A function accessed as a class attribute is normal treated as an 
instance function/method -- with an instance of the class as the first 
argument. A class method takes the class as the first argument. A 
'staticmethod' is a function that takes neither as the first argument 
and, with one esoteric exception, does not need to be a class attribute 
but is for convenience.
