Code Challenge: Teacher Stats

I have been working on this challenge for a really long time. I used the example dict they gave and it seems to work perfectly in workspaces, but I don't understand why it's not working here.

# The dictionary will look something like:
# {'Andrew Chalkley': ['jQuery Basics', 'Node.js Basics'],
#  'Kenneth Love': ['Python Basics', 'Python Collections']}
# Each key will be a Teacher and the value will be a list of courses.
# Your code goes below here.
def num_teachers(argument):
    return len(argument)

def num_courses(argument):
    counter = []
    for each in argument.values():
    return len(counter)

def courses(argument):
    counter = []
    for each in argument.values():
    return counter

def most_courses(argument):
    new_dict = {}
    for each in argument.items():
        new_dict[len(each[1])] = (each[0])
    max_count = max(new_dict.values())
    return max_count

1 Answer

The instructions for most_courses ask to return the name of the teacher not a count of the courses.
