Not too sure about this

This whole challenge has been giving me issues. Can someone help me out? confused on how I should go about this.

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(dic):
    return len(dic)

def num_courses(dic):
    course = 0
    for teachers in dic:
        course += len(dic[teachers])
    return course    

def courses(dic):
    class1 = []
    for classes in dic.values():
        class1.extend([classes])
    return class1
