Python Python Collections (Retired) Dictionaries Teacher Stats

How can I properly format the answer to have <> but not have quotation marks ?

Can anyone provide me with some guidance on how to correctly format the output?

Thanks

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(teachers):
  #storage variables
  max_value = 0
  max_teacher = 'test'
  #for each teacher key in the teachers dictionary
  for teacher in teachers:
    size = len(teachers[teacher])
    if size >= max_value:
      max_value = size
      max_teacher = teacher
  return (max_teacher)


def num_teachers(teachers):
  counter = 0
  teacher_list = []
  for teacher in teachers:
    if teacher not in teacher_list:
      teacher_list.append(teacher)
      counter += 1
  return counter


def stats(teachers):
  output = []
  for teacher in teachers:
    number_of_classes = teachers[teacher]
    instance = ["<{}>, <{}>".format(teacher, number_of_classes)]
    output.append(instance)
  return (output)

The directions read a little confusing, but you don't actually want"<>" in the answer. It just wants a list of lists where the inner lists are in the format [name, number of classes]. You almost have this now, you just need change instance to be a two element list and use the number of classes instead of the names of the classes

def stats(teachers):
  output = []
  for teacher in teachers:
    number_of_classes = teachers[teacher]
    instance = [teacher, len(number_of_classes)]
    output.append(instance)
  return (output)
