Issue with exception handling within a function - Python

Hi All,

I have written this code and when I submit, it produces an error, but everything is fine in my terminal? Please help?!

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

try:
    product_idea = input("What is your product idea? ")
    if len(product_idea) <= 3: #to catch the exception of people trying to use LESS THAN 3 characters
        raise ValueError("Your product Idea is too short. Please re-submit with more than 3 characters.") #raise is used here to capture the error
except ValueError as err: #this is to handle the error from line 8
        print("Oh no! That's not a valid value. Try again...")
        print("({})".format(err)) #this is to handle the error from line 8
else:
        print("Great idea!")

Here is the error I get: Bummer: Oh no, there were 2 problems with your code, check the preview pane for more information

.

You're working way to hard! The challenge only asks you to modify the function itself to test the value ("if") and "raise" an exception. So you only need to add 2 lines of code.

You won't need to get input, call the function, capture an error, or print anything.

I think I'm close...but I think I have the wrong ??? in front of the (3).

def suggest(product_idea): if product_idea < str(3): raise ValueError("Your idea must be longer than 3 characters long") return product_idea + "inator"

Says I have and AssertionError:ValueError not raised : I passed in 'a' and expected a ValueError to be raised.

Any help.... Thanks, K

Kristen, your should always start a fresh question when you have a problem that hasn't already been answered.

But I'll give you a hint that you probably want to test the length of the input instead of the input itself.

And when posting code, always use the instructions for code formatting in the Markdown Cheatsheet pop-up below the "Add an Answer" area. :arrow_heading_down: Or watch this video on code formatting.
