# 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.

def num_teachers(dicti):
    return len(dicti.keys())

def num_courses(dicti):
    total = 0
    for item in dicti.values():
        total += len(item)
    return total

def courses(dicti):
    course = []
    for item in dicti.values():
        for item2 in item:
    return course

def courses(dicti):
    teacher = ["test"]
    max = 0
    for item in dicti:
        if len(dicti[item]) > max:
            max = len(dicti[item])
    return teacher
