Python Python Collections (Retired) Dictionaries Teacher Stats

What is this challenge asking?

Says that it didn't get the expected output. I'm not sure what it is asking for exactly.

# 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 stats(teachers):
  result = []
  for item in teachers:
    result.append('{}, {}'.format(item, len(teachers)).split(','))
  return result

In Task 3, you're asked to: Create a function named stats that takes a dictionary of teachers and returns a list of lists in the format <code>[<name>, <number of classes>]</code>. The input will be the similar to the dictionary shown in the challenge comments.

The expected output will be a "list of lists" where each list is of the format <code>[<name>, <number of classes>]</code>. such as:

[['Jason Seifer', 3], ['Kenneth Love', 2]]
