I assume you're talking about mismatching percent-markers and arguments, there. That's because of a limitation in C's variadic function support, ameliorated somewhat by gcc's warnings system, and completely solved by other languages in which (s)printf can still be an external function, but with reliable type checking. It's not whether it's part of the language or not that does that. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
