why does it say there should be 18 returned items. In the dict given there is only 5 and my code returns all.

# 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 num_teachers(my_dict):
    return(len(my_dict))

    max_count  = 0
    for key in my_dict:
        if len(my_dict[key]) > max_count:
            max_count = len(my_dict[key])
            answer = key
    return answer
