Pivoting on one variable
Pivot tables are the standard way of aggregating data in spreadsheets.
In pandas, pivot tables are essentially another way of performing grouped calculations. That is, the .pivot_table() method is an alternative to .groupby().
In this exercise, you'll perform calculations using .pivot_table() to replicate the calculations you performed in the last lesson using .groupby().
sales is available and pandas is imported as pd.
