teachers.py
# 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(teacher):
    number = len(teacher)
    return number

def num_courses(teachers):
    courses = 0
    for teacher in teachers.values():
        courses += len(teacher)
    return courses    

def courses(teachers):
    all_courses = []
    for teacher in teachers.values():

Here's a few hints:

  • the task is to return the name of the teacher with the most courses
  • the count will be useful for comparing with the number of courses each teacher has
  • when a teacher has more courses than the max, you can update the max and save that teacher's name
  • finally, when the loop is finished, you can return the last saved name
