This simply makes a and b into other names for the class RPS. To 
instantiate a class to make an object, you have to call it:

     a = RPS()
     b = RPS()

This is the right way to define the class (almost: in Py 2, you should 
derive from object). Once you make an object from it, you will have what 
you want:

     class RPS(object):
         def __init__(self):
             self.throw = random.randrange(3)

     a = RPS()
     b = RPS()
     print a.throw
     print b.throw
