User input only takes the last number

[Austin11]

Ok so I redid my code(with the help of my teacher) and now I am running into the problem with validating the user input. Everything works great if they input a float number. yet if they input a string or space I get this error. I have a feeling that my code is stepping on each other somewhere but I can't find it. I don't want to convert the string, just error out nicely. Under the error is my updated code.

Hello there! What you are looking for is the ValueError exception. I believe a good way to implement this would be as follows:

def a_function(): # A Function
    try:
        while:
            # Code is being executed
    except ValueError: # Except when code raises a ValueError
        print("That's not a number!") # Optional
        return a_function() # Then return a_function()

Think about where in your code this may be implemented best!

For more information on Errors and Exceptions, refer to the following python documentation:

Ok, quick question on this. Are you saying I should add a new function in order to satisfy the ValueError or clean up one of my validating functions? Just trying to clarify things so I understand better.
Thanks!
