Need correct code to "Raise" a "ValueError"

I've made a function that creates brand new product names using artificial intelligence.

I have a problem though, people keep on adding product ideas that are too short. It makes the suggestions look bad.

Can you please raise a ValueError if the product_idea is less than 3 characters long? Thanks in advance!

suggestinator.py 
def suggest(product_idea):
    return product_idea + "inator"
raise ValueError:
    len(product_idea) < "3"

Here's a few hints:

  • code must be indented to be considered part of a function
  • the keyword "if" should precede a test, and a colon should go after
  • the "raise" statement should not have a colon after
  • the testing and raising must occur before the function returns
