You now know enough Python to write code that could, by means of selection, respond to user input. I suggest, strongly suggest, that you do Number Guess. It introduces quite a bit of Python that I know you'd like to know. You'll learn how to:
Accept user input.
Catch an error that would otherwise crash your code and, instead of crash, respond in a manner that you choose.
Generate random numbers.
Time a sequence of events.
That's all good stuff!
