Trying to complete this challenge but I am struggling pls help

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

suggestinator.py 
def suggest(product_idea):
    product_idea = input("What is your idea?")
    if int(product_idea) <= 3:
        raise ValueError("Too few characters")
    return product_idea + "inator"

The product idea is provided as an argument, you won't need to "input" anything.

Also, you want to test the length of the argument instead of trying to convert it directly into a number.

You nearly have it, just:

  • delete the line that has "input" on it
  • change "int(product_idea)" to "len(product_idea)"
