I've been away from treehouse for a few days and I need some help here, sorry I ask for so many bailouts.

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):
  teacher_name=''
  max_count = 0

  for teacher in teachers:
    if len(teachers.values()) > max_count:
      max_count = len(teachers.values())
      teacher_name = str(teacher.keys())
    else:
      continue
  return teacher_name

To find the number of courses that the current teacher in the loop has taught use len(teachers[teacher]). Also, since you are looping over the keys of the dictionary, and those are the teachers' names, set teacher_name to teacher.

  for teacher in teachers.keys():
    if len(teachers[teacher]) > max_count:
      max_count = len(teachers[teacher])
      teacher_name = teacher
    else:
      continue
  return teacher_name
