Python Python Basics Functions and Looping Raise an Exception

Someone please help me with this problem

I've made a function that creates brand new product names using "artificial intelligence".

I have a problem though, people keep on adding product ideas that are too short. It makes the suggestions look bad.

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

suggestinator.py
def suggest(product_idea):
    return product_idea + "inator" 
    except ValueError:
    if len(suggest) < 3:
        print("Common man!")

I think the conditional statement 'if len(suggest) <3 should be testing the length of the input variable instead. i.e. 'if len(product_idea) < 3: do something....

I think you are getting part of the idea correct, but we need to put things in the right order and raise an error. First, check if the product_idea length is less than 3-- if it is, raise an error... see below.

Kenneth really wants everyone to learn how to raise errors. It is a great coding convention and he will come back to it again and again. Learn it and live it!

Python is a fun language, best of luck on your journey!

def suggest(product_idea):
    if len(product_idea) < 3: # check for length of less than 3
        raise ValueError # raise a Value Error.  Kenneth emphasizes raising errors in the lecture.
    return product_idea + "inator"

thank you

Why are we using len? why is it not stated in the task at all?

we just used if number_of_people <= 1:

now we're using if len(product_idea) < 3: randomly? Are you guys trying to discourage people into giving up? Every single task I do has some hidden language we haven't used in a few video's.

len is not even used during the two hints!!

This was where I tripped up as well. I understand I had to do something to do with the length of reply but had no idea what or how I should create that in code.

You have demonstrated you are one of the more curious/creative types by coming into the forums to post your comments-- great work! Treehouse is a learning community and we learn from each other.

I find myself refering to the Teacher's notes, offical Python documentation, Stack Overflow, and other Internet resources when I get stuck.

When you get stuck on a challenge, don't let it frustrate you or stop your progress in learning, move forward. You can come back later and try a different approach. I find myself redoing some challenges just because they were interesting or to try different approaches.

Learning in this environment can be challenging; particularly when getting stuck on a problem you have little reference to interpret it through. This challenge has taken me a very long time to tackle and it's slowed my progress substantially.

That is right It took a long time. To solve the problem. And I found out I'm not alone in not understanding. I was totally frustrated. That's the language. It's not easy to get started.
