Next, create a function named num_teachers that takes the same dictionary of teachers and classes. Return the total numb

Why is it telling me my function can not be defined? Down below is my code

teachers = {'Jason Seifer': ['Ruby Foundations', 'Ruby on Rails Forms', 'Technology Foundations'], 'Kenneth Love': ['Python Basics', 'Python Collections']}

def num_teachers(teachers): return len(teachers.keys())

teachers.py 
teachers = {'Jason Seifer': ['Ruby Foundations', 'Ruby on Rails Forms', 'Technology Foundations'], 'Kenneth Love': ['Python Basics', 'Python Collections']}

def most_classes(teachers):
  max_count = {}  

  if (teachers['Jason Seifer']) > (teachers['Kenneth Love']):
    max_count = {'Jason Seifer'}
  else:
    max_count = {'Kenneth Love'}

  for teacher in max_count:
    return teacher

  def num_teachers(teachers):
    return len(teachers.keys())

That is an example dictionary, they use other ones too when they test the code, you have created a function that works for that dictionary. But you need one that can be applied to any dictionary of teachers and return the teacher with the most classes, make a more generic version of the function! Forums are here if you need help if you still don't get it!
