Exercise

Counting up the pairs

You can now create DataFrame of all the permutations of movies that have been watched by the same user. This is of limited use unless you can find which movies are most commonly paired.

In this exercise, you will work with the movie_combinations DataFrame that you created in the last exercise (that has been loaded for you), and generate a new DataFrame containing the counts of occurrences of each of the pairs within.
