when I run this in the workspaces it works but won't let me complete the challenge, please advise

suggestinator.py 
def suggest(product_idea):
    return product_idea + "inator"
try:
    product_idea = input( "please enter your suggestion:  ") 
    if len(product_idea) <= 3:
        raise ValueError(" your suggestion is too short ")
    else: 
        print(suggest(product_idea))
except ValueError as e:
    print(e)

There's a few issues here:

  • the instructions only ask you to raise the exception, you won't need try or except
  • all the testing must be done before the return
  • the error should occur only when the idea is less than 3 characters (not when it equals)
  • the instructions do not ask for anything to be printed
  • the passed argument is what should be tested, you won't need to input anything
