Note that your problem is not related to mangled names: replacing __one by  
one raises a similar exception.
Remember that "self" is not implicit: you must use self.__one()

"private" methods (and atributes in general) use a single underscore:  
_one. Double underscores __one are reserved for the (rare) cases when you  
want to ensure unique names (or name clashes are expected).
