What I am doing wrong. Please help

Code returns list of all courses but check return Bummer Couldn't find 'courses'. Yet function is named courses as requested

# 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(dict):
    num_teachers = 0
    for teacher in dict:
        num_teachers += 1
    return num_teachers

def num_courses(dict):
    num_courses = 0
    for teacher in dict:
        num_courses += len(dict[teacher])
    return num_courses

def courses(dict):
    courses_list = []
    for teacher in dict:
        for course in dict[teacher]:
    return course_list

Hi there,

It'll say "couldn't find 'courses'" if the code won't run due to a syntax error.

I'll have a look and see what I can help you with.


I'm still super new at this, but should return course_list be return courses_list?

Your list name is "courses_list" but you're returning "course_list" without an s on courses.

Good spot! :+1: :smile:
