The dataset has been downloaded from http://datamarket.com and is also available in the datasets folder of this book's GitHub repo.

We start by importing the packages required for running this example:

from __future__ import print_function 
import os 
import pandas as pd 
import numpy as np

This is followed by reading the data from the CSV file in a pandas.DataFrame and displaying shape and the first 10 rows of ...
