Python Python Collections (Retired) Dictionaries Teacher Stats

Don't know whats wrong. Please Help. Tried to do it with what I have learnt solely from treehouse.

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(dict):
  var_x = {}
  for key in dict:
    var_x[key] = len(dict[key])

  var = 0
  for i in dict.values(): 
    if i > var:
      var = i

  winner = None
  for key in dict:
    if dict[key] == var:
      winner = key

  return winner

Hi Finley,

Looks like you are close, but perhaps overcomplicating things a little bit. I posted my answer below. I set up a winning teacher variable and a max number of classes variable, then iterated over the dictionary, replacing the winner with the teacher name and set the max_classes if the teacher was teaching more classes than previously recorded.

Hope that helps!

def most_classes(dict):
  winner = None
  max_classes = 0
  for teacher in dict:
    if len(dict[teacher]) > max_classes:
      winner = teacher
      max_classes = len(dict[teacher])
  return winner

Thanks
