task 4 code challenge, teachers.py...How do you get the values into one, big list?

It is saying I get 25 responses, when there should be 18.

Here is what I have for the final task:

def courses(teachers_dict):
    all_courses = []
    for value in teachers_dict:
      all_courses.extend(teachers_dict.values())
    return all_courses

for value in teachers_dict:
    all_courses.extend(teachers_dict.values())

This is putting all of the values in teachers_dict into all_courses as many times as there are keys in teachers_dict. You need to loop through teachers_dict.values() instead.

for list_of_classes in teachers_dict.values():

Should get you started.
