The coding challenge for teacher stats: task 4 of 5

# 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.

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


def num_teachers(teachers_list):
     return len(teachers_list)

    count = 0
    for values in teachers_list.values():
        for course in values:
            count += 1
    return count

def courses(teachers_list):
    courseList = []
    for values in teachers_list.values():
        for course in values:
            courseList.append(course)
    return courseList

def most_courses(teachers_list):
    max_courses = [max(len(value) for value in teachers_list.items())]
    for teacher,courses in teachers_list.items():
        for course in courses:
            if len(course) == max_courses:
                return teacher
