Task 2 works in VS code but not here

Why does this code work in my text editor but not here at the challenge?

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.
def num_teachers(dict):
    num_of_teachers = 0
    for key in dict.keys():
        num_of_teachers += 1

    return num_of_teachers

def num_courses(dict):
    num_courses_total = 0
    for course in dict.values():
        num_courses_total += course

    return num_courses_total
