What code can I use to detect if a string comes back less than 3 characters long?

I know I can't use < 3 or < (" ") with three spaces. Would I need to create a new function for this?

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

Hi there. Kyler Aagard! I received your request for assistance. I feel like you might have forgotten the len() which will return the length of a string (or list or dictionary).

For example:

school = "Treehouse"
school_length = len(school)

At the end of this, school_length will contain the value 9.

Hope this helps! :sparkles:
