Getting ready

A scikit-learn program begins with several imports. Within Python, preferably in Jupyter Notebook, load the numpy, pandas, and pyplot libraries:

import numpy as np    #Load the numpy library for fast array computations
import pandas as pd   #Load the pandas data-analysis library
import matplotlib.pyplot as plt   #Load the pyplot visualization library

If you are within a Jupyter Notebook, type the following to see a graphical output instantly:

%matplotlib inline
