Which is what I do...calling only those necessary until the all/any condition has been met. :-) If you create the list of things to iterate over by calling them as you create the list, then you don't save much of anything. If you only call until one of them breaks the any/all construct, you save all the subsequent function calls. -tkc -- https://mail.python.org/mailman/listinfo/python-list
