I wrote the below code

    global EVENT_COUNT
    EVENT_COUNT = 0
    class PySubclass(CEvent40, ):
        def add_Act(self, value):
            self.Act += value
        def remove_Act(self, value):
            self.Act -= value
        def call(self):
            self.Act(1, 2)
    x = PySubclass()
    def f(x, y):
        EVENT_COUNT += 1
        print x, y
    x.add_Act(f)
    AssertErrorWithMessage(TypeError, 'BoundEvent    is    not    callable', x.call)

What's a good function header?
 ... Give me a Python program to print x, y?

#Here is Python program to print x, y
