I am distracted with the example provided in the post. I am pretty sure that most pandas users will just put course_ids on the columns. I mean the shape of the user_courses dataframe is not suitable for the task. (user_courses
.set_index(["student_id",
"course_id"])
.unstack()
.apply(lambda x: x+1))
