Not clearly understanding the concept.

Could someone please tell me what is wrong with this code. I am a complete beginner and am having understanding certain concepts. I tried to use the .len property to target the challenge but it did not work.

suggestinator.py 
def suggest(product_idea):
    if product_idea.len < 3:
        raise ValueError("Please enter a name with atleast three characters.")
    return product_idea + "inator"

len is a function that takes in a string (actually, it takes in any kind of iterable, but that is covered in another course), and it "returns" (spits out) a number, the length of the string (or iterable).

For instance...

(Pretend I'm in the Python Shell.)

>>> len('abc')
3
>>> len('hello world')
11
>>> len('1 2 3')
5
>>> len('  ')
2

:warning: Note that len counts spaces/tabs/punctuation as characters, too. So this means len('! ? $') would return 5.

I hope this helps! :grin:

Happy coding! :zap: ~Alex
