I am having trouble list a single list of all the classes in a dictionary.

I am really stuck on this question.

teachers.py 
dictionary = {'Andrew Chalkley': ['jQuery Basics', 'Node.js Basics'], 'Kenneth Love': ['Python Basics', 'Python Collections']}

def num_teachers(dictionary):
    number = len(dictionary)
    return(number)

num_teachers(dictionary)

def num_courses(dictionary):
  ctr = sum(map(len, dictionary.values()))
  return(ctr)

num_courses(dictionary)

def courses(dictionary):
    school= list(dictionary.values())
    for course in school:
        for classes in course:
        print(classes)

courses(dictionary)

I think you mostly have it. Where you have print(classes), you could, instead, append the classes to some classes_list and then return the classes_list.

Hope that helps!
