Note that this is actually a list, not a tuple as your subject suggests. For the difference, take a look at this: http://www.python.org/doc/faq/general.html#why-are-there-separate-tuple-and-list-data-types Also, it's generally considered bad form to shadow built-in type names like list. This prevents you from using methods in the list scope and makes for potentially confusing bugs. > while select != list[0] or list[1] or list[2]: This actually behaves as though you wrote this: while (select != list[0]) or list[1] or list[2]: The since list[1] always evaluates to a true value (non-empty strings are true), the while loop body will always execute. Fortunately, python has a very simple way of doing what you want: vehicles = ("airplane", "car", "boat") select = vars while select not in vehicles: select=raw_input("Wich vehicle?") -- Brian -- http://mail.python.org/mailman/listinfo/python-list
