You are making two mistakes here.

better off defining the method 'f' as follows:

    def f(self, x):
        return 'hello world'

Note the explicit 'self' parameter.

> >>> x = MyClass

Here, you are simply making 'x' an equivalent name to 'MyClass'.  To
instantiate a member of the class, do it like this:

>>> x = MyClass()

Note the parentheses.

With those two changes, you should be able to do this:

>>> print x.f(1) 
hello world
>>>
