Exception Handling

Question

anyone could tell me what I am making wrong with the code, because can't pass all of it, just pass 3 of the 4 question .
You are making a program to manage user names.
A valid username needs to be minimum 4, maximum 20 characters long.
Create a program to take a string as input, check its length and output "Valid" if the name is valid, or "Invalid", if it is not.
