Tidy data
Reshaping your data has several applications. One important application is to switch from a data analytics friendly to a reporting friendly format. This concept is further expanded in the Tidy data paper by Hadley Wickham.
Data in a tidy format also allows you to perform groupby operations as seen in the previous exercise.
In this exercise you will use melt() and .pivot_table() from pandas to reshape your data from one
shape to another. Remember that when you call .pivot_table() on your data, you also need to call the .reset_index() method to get your original DataFrame back.
Before you start reshaping the airquality DataFrame, inspect it in the shell. We've imported pandas as pd.
