Stuck on challenge 3 of Teachers.py

I'm not appending the new list correctly but I'm not sure how to do that.

teachers.py 
# 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(dicts):
  max_count = {'name':'teacher','class':0}
  for teacher in dicts:
    value = len(dicts[teacher])
    if value > max_count['class']:
      max_count = {'name':teacher,'class':value}
  return max_count['name']
def num_teachers(dicts):
  return len(dicts)
def stats(dicts):
  teacher_list = []
  for teacher in dicts:
  teacher_list.append(['name', max_count['class']])
  return teacher_list

You are on the right path. Here is the corrected code:

def stats(dicts):
  teacher_list = []
  for teacher in dicts:
    # increased indent to make it part of the for loop
    # use teacher instead of 'name' as the first item
    # was getting 'max_count' not defined error
    # get the number of courses using 'len(dicts[teacher])'
    teacher_list.append([teacher, len(dicts[teacher])])  # was: max_count['class']
  return teacher_list
