Yup! Sorry about my tone for its stridency. But I just got concerned that the original poster seemed content about turning the chain of if statements into a table definition. To my mind, they're very closely related, data and control. I'm trying to push the OP to realizing that if they are doing this, they are still enumerating all the decisions. Maybe it's not in the form of a chain of if statements, but it's still reflected in the structure of the table.
(It's the same reason I get concerned when I see students not recognize the similarities between if statements and polymorphism: it's all about transmogrifying control flow and data structures.) Let me say that if there's non-uniformity among the choices, then the table lookup approach (a dispatch table) is probably the right tool. If there's uniformity, then a computational approach should be considered. _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
