How do i make this code work more than ounce while in the blender game engine?

Please have a thought on this:
Is cycle a function?
Agoose77 wrote this code ask him.

What exactly is the problem? What happens when you try to run it more than once?
Also, it looks like Cycle objects can act as a function because they’re callable; the call method was defined in the Cycle class.
The enemy would not go near the closet cube with the property cow when i controlled that cube with a keyboard sensor and also go back to the other cube with the property cow.It is supposed to go backwards and forwards from two cubes that are the nearest that have the property cow out of ten cubes with the property cow.
