#  'Kenneth Love': ['Python Basics', 'Python Collections']}
#
# Each key will be a Teacher and the value will be a list of courses.

In multi-task challenges, each task builds on the previous one(s). So the num_teachers function you created for task 1 should remain as-is when you add the num_courses function. But in the code above it seems to be missing.

Did you get a message like "Oops! It looks like Task 1 is no longer passing."? The task 2 code is fine, put it with the task 1 code and you should pass to the next level.
