Teacher stats

The fourth step

Bummer! You returned 5 courses, you should have returned 18.

Do i have to add something here?

teachers.py
# The dictionary will be something like:
# {'Jason Seifer': ['Ruby Foundations', 'Ruby on Rails Forms', 'Technology Foundations'],
#  'Kenneth Love': ['Python Basics', 'Python Collections']}
#
# Often, it's a good idea to hold onto a max_count variable.
# Update it when you find a teacher with more classes than
# the current count. Better hold onto the teacher name somewhere
# too!
#
# Your code goes below here.

my_dict = {'Gilang' : ['Basic of Nuclear Technologies', 'Practical Quantum Physics', 'The Philosophy of Physics'], 'Yohannes' : ['Energy Engineering', 'Green Technology'], 'Audrey' : ['The Psychology of Patriotism']}

def most_classes(my_dict):
    max_count = 0

    most_class = ""

    for teachers in my_dict:
        if len(my_dict[teachers]) > max_count:
            max_count = len(my_dict[teachers])
            most_class = teachers
    return most_class

def num_teachers(my_dict):
    teacher = len(my_dict.keys())
    return teacher

def stats(my_dict):
    the_list = []

    for teachers in my_dict:
        new_string = [teachers, len(my_dict[teachers])]
        the_list.append(new_string)
    return the_list

def courses(my_dict):
    single = []
    for value in my_dict.values():
        single.append(value)
    return single

:point_right: Perhaps you meant to use extend?

The append method adds a list as a single new element, but extend adds each item from a list as a separate element.
