I am getting exactly what is expected in my ide, what is wrong with the challenge, tired of bummers on correct answers.

# 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.

    i = 0
    for key in dict_teachers:
        i += 1
    return i

def num_courses(dict_teachers):
    i = 0
    for value in dict_teachers.values():
        i += len(value)
    return i

def courses(dict_teachers):
    course_list = []
    for value in dict_teachers.values():
        course_list += value

    return course_list

    max_count = 0
    for teacher, courses in teachers_info.items():
        if len(courses) > max_count:
            max_count = len(courses)
            max_teacher = teacher
    return max_teacher

    teach_n_subj_list = []
    for teacher, course_list in dict_teachers.iteritems():
        temp_list=[teacher, len(course_list)]
        teach_n_subj_list.append(temp_list)
