Program doesn't recognise index function

Hi,

My code throws error that "dict_values" object has no attribute index.

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.

teachers = {'Jason Seifer': ['Ruby Foundations', 'Ruby on Rails Forms', 'Technology Foundations'],'Kenneth Love': ['Python Basics', 'Python Collections']}

def most_classes(teachers):
    count = 0
    subject_dict = {}
    for key,values in teachers.items():
        new_values = len(values)
        subject_dict={key:new_values}

    values = subject_dict.values()   
    highest = values.index(max(values))
    keys = subject_dict.keys()
    max_teacher = keys[highest]

    return max_teacher

def most_classes(teachers):
    cmax = 0
    cteacher = ""
    for key,values in teachers.items():
        current = len(values)
        if current > cmax:
            cteacher = key
            cmax = current

    return cteacher 

I hope this helps
