Answer 1

What is represented by the "..."? If you actually have "..." in your code, that's a big no-no. You need another thing. If you want it to reiterate, use "continue".

Oh. And helpful tip: this app runs a version of Python that is different from your computer's IDLE. So programs that work there might not work here.
