Code works on personal terminal but challenge not passing

Please see attached code. I run this at home and get an output of 4 which is correct. Not sure why the code challenge is not being accepted. Thank you

teachers.py 
# 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.

arg = {'Andrew Chalkley': ['jQuery Basics', 'Node.js Basics'],
  'Kenneth Love': ['Python Basics', 'Python Collections']}

def num_teachers(arg):
     return len(arg)

def num_courses(arg):
    new_list = []
    for value in arg:
        new_list.append(len(arg[value]))
    total = sum(new_list)
    return total

which step are you on? I just copied your code and it passed up to step 3 where you create a new function that you do not have in your code block here.

Thank you for your response. I just figured it out. I need to just add # to arg input. I needed that part for my own terminal but Treehouse passes its own argument.
