Exercise

.groupby() and .sum() together

If you looked at our transaction-level data in the last exercise, you may have noticed some new columns, like movie_genre and ticket_type. In this exercise, we'll focus on summarizing our data by ticket_type. Tickets can be priced for adults, seniors, or children, and the ticket_type column contains the ticket type purchased during each transaction.

Let's use .groupby() and .sum() to create a summary table to understand how many of our tickets are of each ticket type.

The pandas package and the sales dataset has already been loaded for you.
