"Input from the user" could mean a lot of things. Record gestures from the camera? Voice input via microphone? Scan a document? Move the mouse? This question can hardly be answered.
I'd agree with tomerikoo's suggestion, banning input and reading directly from sys.stdin is probably the most straightforward way to handle this, though slightly less convenient.
