The Best CombinationThe Best Combination

Interesting! The most profitable weeks are the second to last weeks of December and November. Now, let's answer the question: What was the best selling week and store? Since our data is already weekly, we won't need to group observations this time.


  1. Select the 'Store', 'Date', and 'Weekly_Sales' columns.
  2. Sort the values of the 'Weekly_Sales' column in descending order (not ascending).
  3. Display the first 10 rows of the obtained dataframe.

Do not worry about syntax, pandas allows splitting methods by lines.

Everything was clear?
