Apr 25, 2014 · How do I ask for valid input instead of crashing or accepting invalid values (e.g. -1)? The simplest way to accomplish this is to put the input method in a while loop. Use continue when you get bad input, and break out of the loop when you're satisfied. Use try and except to detect when the user enters data that can't be parsed. try:
