Which line of code could raise the ValueError exception?

That line should be in the try block.

I also suggest unique error messages. If the user does not enter a 
number tell him so.

Also you need a way to break out of the loop once user enters a valid key.

Consider using the isdigit function to test the input instead of an 
exception.
