Exercise

Book genre popularity

Previously, you worked with a dictionary containing information about authors and the number of books that they have written.

In this exercise, data about the same authors has been aggregated to create a new dictionary called genre_sales, where the keys are the genre and the values are the average sales for that genre among the 20 most popular authors.

Your job is to find the most and least popular genres among these authors, along with their average sales revenue.

Instructions

100 XP

  • Print the genre with the largest average sales.
  • Next, filter where average_sale is equal to the smallest sales revenue (80000000).
  • Lastly, print the genre with the smallest average sales.
