Teacher Stats.. 3 / 4. No Longer Passing Task 1?

# 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.

    max_count = 0

    most_class = ""

    for teacher in dictionary:
        if len(dictionary[teacher]) > max_count:
            max_count = len(dictionary[teacher])
            most_class = teacher
    return most_class
