teachers.py
# 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(a):
    return len(a)
def num_courses(dic):
    number = 0
    for v in dic.values():
        number += len(v)
    return number
def courses(dic):
    course_list = []
    for v in dic.values():

        for a in v:
            course_list.append(a)
    return course_list
def most_courses(dic):
    m_courses = 0

    for k , v in dic.items():
        if len(v) > m_courses :
            m_courses = len(v)
            teacher = k
    return teacher 
def stats(dic):
    fin_list = []
    for k , v in dic.items():
        pri_list = []
        pri_list.append(k)
        pri_list.append(len(v))
        fin_list.append(pri_list)

Hi, have a look at your indentation for your return statement.

def stats(dic):
    fin_list = []
    for k , v in dic.items():
        pri_list = []
        pri_list.append(k)
        pri_list.append(len(v))
        fin_list.append(pri_list)

return fin_list

As far as I understand it, python doesn't use curly braces like other languages it uses indentation. So the function and the return statement are seen as separate. So it should look like this.

def stats(dic):
    fin_list = []
    for k , v in dic.items():
        pri_list = []
        pri_list.append(k)
        pri_list.append(len(v))
        fin_list.append(pri_list)

    return fin_list
