I have spent the past hour trying to figure it out.

You were super close switch the return line to the bottom. With def func you want the return to be at the bottom. You also need to check the length of your string that is being inputted. Use the len() method to measure strings.

Here is the code if you get stuck.

def suggest(product_idea): if len(product_idea) < 3: raise ValueError("More than 3 characters are required") return product_idea + "inator"

Zhang, you have the right idea, however you are returning a result before you perform the character length check. Try switching around the order to fix the issue.
