Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "We will use the os package in the operating system's dependent functionality, and the pandas package for data manipulation."

A block of code is set as follows:

import os
import pandas as pd

# Set working directory as per your need
os.chdir(".../.../Chapter 1")
os.getcwd()
