Hello, im stuck trying to raise an exception.

Hello! They want me to raise an exception for when the user tries to add a word thats less than three letters. What am i doing wrong? Im really stuck, thanks!

suggestinator.py 
def suggest(product_idea):
    if product_idea < 3:
        raise ValueError("Your name is to short, try again")
    return product_idea + "inator"
try:
    product_idea = int(input("Whats your idea?   "))
except ValueError:
    print("Ops, your name doesnt work, try again!  ")

Hi Simon,

There's no need to use try/except blocks for this task or handle the user input. All we need to do is raise a ValueError if the product idea has less than 3 letters.

When you're checking this condition you're code as posted checks the value of product idea, we want to check the number of letters. product_idea is getting "inator" a String literal added on the end of it, so product_idea is probably a String. This means we can use the len() function to return the number of letters.

Your initial raising of the value error would have worked fine if the if statement was checking the length of product_idea against 3 instead of product_idea's value.

def suggest(product_idea):
        if len(product_idea) < 3:
                raise ValueError("Your name is too short, try again")
        return product_idea + "inator"
