Is it possible to do simple a if-then-else sort of an algorithm? Below is some pseudo code: if state == "ABC": do_something() change state to DEF if state == "DEF" perform_the_next_function() ... I have a class to which certain values are passed from a GUI and the functions above have to make use of those variables. How do I go about doing this? I have the following algorithm: class TestClass(): def __init__(self, var1, var2): #var1 and var2 are received from a GUI self.var1 = var1 ... if state == "ABC" doSomething(var1, var2) .. Could someone point me in the right direction?

That is, function A does its thing, gets to a new state, and returns as one of its return arguments the key into the dictionary that points to the next function_name to be called based on that new state. Stackoverflow has a couple of compact examples here: http://stackoverflow.com/questions/715457/how-do-you-implement-a-dispatch-table-in-your-language-of-choice Bill
