What do seniors like?
Let's use what we've learned so far to create a summary table, sort for a specific subset of that table, sort the values, and print the most important results. We'll use these techniques to answer the question "what movies do seniors like best?"
Note that in this exercise, we'll group by a list directly in the .groupby() method, as opposed to the video exercise, where we first assigned a list to a variable.
