num_courses code wrong?

i tried it in the workspace and it returned the number that i wanted. but why is this considered wrong by the program?

# The dictionary will look something like:
# {'Andrew Chalkley': ['jQuery Basics', 'Node.js Basics'],
#  'Kenneth Love': ['Python Basics', 'Python Collections']}
# Each key will be a Teacher and the value will be a list of courses.
# Your code goes below here.

def num_teachers(dicti):
    return len(dicti.keys())

def num_courses(dicti):
    total = 0
    for item in dicti.values():
        total += len(dicti.values())
    return total

Hi there,

I think you can just use total += len(item) inside your for loop. The variable item holds all the values, so just increment its length onto the total counter.
