code didn't work on Treehouse

My code works on console but in challenge it shows task 1 no longer passing. what might be the problem?? 

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

def most_classes(dic):
  m_c=0

  for k in dic:
    n_c=len(dic[k])
    if n_c > m_c:
      best_teacher=k
  return k

def num_teachers(dic):
  count=0
  for teacher in dic:
    count+=1
  return count

[MOD: added ```python formatting -cf]

In most_classes you are returning k which is the last teacher in the loop instead of best_teacher
