C++ functors (analogous to Python callables) do what you want and a
lot more. I am sure your problem does not need to get to this level,
but here is some food for thought. Notice the absence of
if-statements.

class F:
    def __call__(self):
        print "First pass"
        self.i = [10, 11]               # initialization
        self.first_call = self.__call__ # metaprogramming fun
        self.__call__ = self.call       # metaprogramming fun
        self()
    def call(self):
        self.i[0] += 1
        print self.i[0]
    def reset(self):
        self.__call__ = self.first_call # metaprogramming fun
f = F()

f()
f()

f.reset()
f()
f()

The full power of functors/callables only shows up when you combine
them with inheritance.
