its telling me that ValueError isn't raised

suggestinator.py 
product_idea = 3


def suggest(product_idea):
    if product_idea != 3:
         raise ValueError("add more letters")
    return product_idea + "inator"
print(format(suggest))

The instruction say to "raise a ValueError if the product_idea is less than 3 characters long". There's a few issues here:

  • the length of the string should be tested, not the string itself
  • the test should check for less than 3 instead of not equal to 3
  • you don't need to add any code outside the function
  • you don't need to print anything

I changed product_idea = 3 to product_idea = Len("abc"), != to < , and deleted everything after return but now its throwing this error: File "", line 4, in suggest TypeError: '<' not supported between instances of 'str' and 'int'

A couple more hints:

  • you should not be creating a variable (or adding any other code) outside of the function
  • the "len" function can be used inside the function in the comparison, but it must be spelled in lower case
