Do you actually write loops like this? If this appeared in a code review, first we'd have a conversation about what this code was meant to do, and then I would ask, "Why aren't you using a for loop?" I suspect most Python programmers would be similarly confused about why you aren't using one of the central constructs of the language. What's next? "Why have both if and while? A goto will work for both!" --Ned. -- https://mail.python.org/mailman/listinfo/python-list
