Python does not have a "switch" construct, the reason is that even in C "switch" has a poor profile compared to if-else-if and some severe limitations to boot.

It's an artifact of me being on Windows and not needing to return exit vals ;-)Like I said, though, I wouldn't code exactly that way - at a minimum I'd wrap the base level code as a main() function though I'd be more likely to do everything in a class.

Your code has a MAJOR flaw, though

Bad Bad Bad!! What happens if a bug crops up in one of the functions which triggers a KeyError? If you use lookup tables for functions/methods, always get the function first before calling it (which is why the func() call appears in the else: block, where it will not trap KeyErrors).
