dictionary

help am facing challenges

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.
dicts = [
  {'Jason Seifer': ['Ruby Foundations', 'Ruby on Rails Forms', 'Technology Foundations'],
'Kenneth Love': ['Python Basics', 'Python Collections']}
  ]
def most_classes(dicts):
  for key in most_classes:
      return(most_classes)

Try this code snippet:

def most_classes(teachers):
  max_count = 0
  teacher_name = ""
  for classes, name in zip(teachers.values(), teachers.keys()):
    if len(classes) > max_count:
      max_count = len(classes)
      teacher_name = name
  return teacher_name

Also, there is no need to write the "teachers" dictionary. (don't worry; that doesn't mean that you shouldn't)

Hope that helps! ~xela888
