Challenge Task 3/4 - "most_classes" excercise

# 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(teachers):
  maxNum = 0 
  name = ''
  for k,v in teachers.items():
    if len(v) > maxNum:
      name = k
      maxNum = len(v)
  return name

def num_teachers(teachers):
  count = 0
  for k,v in teachers.items():
    count += 1
  return count

def stats(teachers):
  name = []

  for k,v in teachers.items():
    name.append(k)
    name.append(len(v))
  return name
