1,203 PointsSomeone 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!
def suggest(product_idea):
return product_idea + "inator"
except ValueError:
if len(suggest) < 3:
print("Common man!")

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"

3,029 PointsWhy 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!!

Treehouse Moderator 28,720 PointsYou 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.

1,431 PointsThat 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.

1,431 Pointsok plz i solve this code too but get fail
