To start, let me arouse your interest by showing you some analytical and graphical capabilities of Python. I have explained the code just briefly in this section; you will learn more about Python programming in the rest of this chapter. The following code imports the libraries required for this demonstration:
import numpy as np import pandas as pd import matplotlib.pyplot as plt
Please note that Python is indent sensitive. Every space counts. You should be very careful especially when you use commands that span multiple lines. Just leave the default indent of a new line created by VS; if you delete or add a space, the code does not work.
Then we need some data. I am using the same data from the AdventureWorksDW2014 ...
