Importing libraries

The following code, and indeed most of the code in the book, first requires the installation of the yfinance package:

pip install yfinance 

yfinance can then be imported:

import yfinance as yf

For this chapter and the rest of the book, we will also be working with pandas, numpy, and matplotlib. So, please remember to import them first:

# Import Libraries
import pandas as pd
import numpy as np
%matplotlib inline
import matplotlib.pyplot as plt
