I don't even know where to begin with this one.

The challenge is to create a function named most_classes that takes a dictionary of teachers. Each key is a teacher's name and their value is a list of classes they've taught. most_classes should return the teacher with the most classes.

Not sure how to start with this one.

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(**teacher):
    max_count = 0

This code will work, with a play-by-play of why it works. I hope that this is helpful.

def most_classes(teachers):
    # Provide empty variables
    most_classes = 0  # Value to compare against
    teacher = None  # Teacher value to return

    for teacher in teachers:  # Loop through teachers
        if len(teachers[teacher]) >= most_classes:  # Compare teacher's classes against most_classes
            most_classes = len(teachers[teacher])  # Update most_classes
            teacher = teacher  # Update teacher's name
    return teacher  # After forloop finishes, return the teacher

Hi I am not sure it is absolutely right, but it should make a job 

# create a function named most_classes hat takes a dictionary of teachers
def most_classes(dictionary_of_teachers):

# Better hold onto the teacher name somewhere and more classes too!
    teacher = ""
    most_clases = 0
    for name_of_teacher in dictionary_of_teachers:
        count_of_clases = 0
        for class_ in dictionary_of_teachers[name_of_teacher]:
            count_of_clases += 1
            if count_of_clases > most_clases:
                teacher = name_of_teacher
                most_clases = count_of_clases
    return(teacher)
