In this case, I think the else block is unnecessary, since you already have that same line of code in the try block; there is no need to repeat it. Instead of putting in ValueError, try using TypeError. I think the TypeError is what you want because it indicates that the wrong type of input was used (so a string instead of an integer, etc.) Also, you should probably put something inside your except block, like return "That's not a number!" so that when a string, for example, is passed into your function, there will still be an output.
