I'm trying to raise a value error, and it'a not working out

I think I'm not using the length properly. I keep getting this message. Bummer: Oh no, there were 2 problems with your code, check the preview pane for more information. The preview is saying something about object type int. I think it's how I'm declaring my len()

suggestinator.py 
def suggest(product_idea):
    if product_idea < len(3):
        raise ValueError("Your product_idea needs to be more than 3 characters")
    return product_idea + "inator"

Hiya there! You're right about "len()" method though but if you check the docs, you'll find that len() method takes in an array, not int but it throws an Int. So yeah your answer should look like this:

def suggest(product_idea):
    if len(product_idea) < 3:
        raise ValueError("Your product_idea needs to be more than 3 characters")

    return product_idea + "inator"

I hope it helped!

james mchugh A simple super helpful tip: Download docs for whatever IDE you're using and you can get documentation right in your IDE. I'd highly recommend PyCharm 'coz it'll help you a lot, plus its a go-to IDE for Python in Startups to Enterprises. Press ctrl+Q on any method and you'll get docs right in your IDE. It's that simple and informative (:
