Raising value error

I'm trying to raise a value error but my code isn't working, don't know exactly what i'm doing wrong.

suggestinator.py 
def suggest(product_idea):
    return product_idea + "inator"
    if suggest <= len(3):
        raise valueError()

I see a few issues:

  • the testing (and possible raising) must be done before the return
  • name 'suggest' is not defined
  • an object of type 'int' (such as 3) has no len()
  • you'll want to test if the length of the argument is less than 3
  • "ValueError" is not a function (and should be spelled with a capital "V")

Hey Matthew,

It looks like you're returning product_idea + "inator" before your code has a chance to run your if statement.

  1. Try moving your return statement to after the if statement
  2. You should be referencing the length product_idea since you can't reference a function you're declaring and product idea is a string based on the concatenation in your return statement.
  3. ValueError requires a capital V and E
  4. You might also want to include an error message when you're raising an error to make it more user-friendly; alternatively you can use the shorthand raise ValueError (no brackets)

I hope this is helpful!

def suggest(product_idea):
    if len(product_idea) <= len(3):
        raise ValueError('Sorry, that's too short!')
    return product_idea + "inator"

The correct answer should be.

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

Hope this helps.
