What's the expected output for task 3 of the the Python collections challenge?

# 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.
def most_classes(dict_teachers):
  max_count = 0
  teach_max = ""
  for teach in dict_teachers:
    if len(dict_teachers[teach])> max_count:
        max_count = len(dict_teachers[teach])
        teach_max = teach
  return teach_max

def num_teachers(dict_two_teach):
  return len(dict_two_teach)

def stats(dict_three_teach):
  for teach in dict_three_teach:
    return (teach, len(dict_three_teach))
