The output from my function is {'Django Basics', 'Python Basics', 'Setting Up a Local Python Environment', 'Python Collections', 'Object-Oriented Python', 'Flask Basics'}
Is the grader looking for something else?

56,413 PointsI just finished banging my head on this challenge and finally got it to pass. The trouble is the challenge may be worded that it wants all course titles, it really wants only the titles of the prerequisites. So the first title, 'Django Basics', has to be skipped.
