Head on:)
but head up, Python is very flexible, so build your own overloader

class Overloaded:
    __overload = {}

    def f(self, *args):
        apply(self.__overload[len(args)], (self,) + args)

    def f1(self, a):
        print a
    __overload[1] = f1

    def f2(self, a, b):
        print a, 'and', b
    __overload[2] = f2


u = Overloaded()
u.f('spam')
u.f('spam', 'spam')
