Need help with this please :)

teachers.py 
# The dictionary will look something like:

dic = {'Andrew Chalkley': ['jQuery Basics', 'Node.js Basics'],
  'Kenneth Love': ['Python Basics', 'Python Collections']}
def num_teachers(dic):
    num = 0
    for key in dic.keys():
        num += 1
    return num    

def num_courses(dic):


# Each key will be a Teacher and the value will be a list of courses.
#
# Your code goes below here.
