You need to convert your string to an integer, the 'smaller than' ( '<' ) comparison operator don't work with strings.

it's the raise an exception challenge in python basics we're trying to raise a ValueError exception if the product idea, which the user inputs is less the 3 characters long

def suggest(product_idea):
    if int(product_idea) < 3:
        raise ValueError
    return product_idea + "inator"

Okey, python has a built-in function called len(), it takes a string as argument, and returns its length as an integer, which can be used with the comparison-operator.

    def suggest(product_idea):
        if len(product_idea) < 3:
            raise ValueError
        return product_idea + "inator

len is the action that makes sure to count the words right? If that makes sense I am literally just starting out, and I am loving treehouse over codecademy but somethings I still need help on.
