Can you please raise a ValueError if the product_idea is less than 3 characters long? product_idea is a string. Thanks i

where should i test the length of the string instead of the string itself will int() be needed anywhere

suggestinator.py 
def suggest(product_idea):
    if product_idea < 3:
        raise ValueError("characters too short")
    return product_idea + "inator"

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

I'm stuck on this one as well! I used the same code as suggested by Kennedy above and got the following error: AssertionError: None != 'baconinator' : I passed in 'bacon' and expected 'baconinator', but got 'None'

Try creating a fresh question where your exact code will be shown.

Yea, Kennedy realized he was testing the string itself instead of the length of the string. He just forgot to use Markdown formatting on the code in his answer.

You won't need int(), but you might need to use the len() function.   :wink:

I'm running into an issue where I keep getting an EOF error on line 5 which is my input line and I'm assuming it has something to do with product_idea being a string can someone please hint me towards what is wrong with it?

def suggest(product_idea): return product_idea + "inator"

product_idea = input("whats your product idea? ")

if len(product_idea) < 3: raise ValueError("please 3 characters or more")
