If really beginning, an overview of this whole idea of control structures makes sense, such as this wikipedia article: http://en.wikipedia.org/wiki/Control_flow Then explain how Python is very minimalist in its approach, unlike some languages, which try to provide all kinds of control structure semantics, including multiple case loops (do... case... case...) which Python famously does not natively have either. > they find the "while" logic to be unintuitive, and I often find myself > feeling the same way: crafting it with the until logic, and then reversing > it. I wouldn't make "intuitive" the guiding light in all cases, as it's often just code for "conditioned reflex" or "what we're used to." Usually beginners outgrow their initial discomfort, like when learning to drive stick instead of automatic or whatever. Kirby -- http://mail.python.org/mailman/listinfo/python-list
