Python Python Collections (Retired) Dictionaries Teacher Stats

i am stuck on this dicts challenge

i don't even know where to start on def stats(), can you please assist if you can

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):
  max_count = 0
  busy_teach = ""
  for teacher1, teacher2 in teachers.items():
    if len(teacher1) > max_count:
        max_count = len(teacher2)
        busy_teach = teacher1
        return(busy_teach)

def num_teachers(total):
  return len(total)

def stats():

1 Answer

def function that takes argument, 
make tuple, 
for argument that has tuple, append, teacherlist append
return that teacherlist

how does this work? =)
