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: "I used the sed syntax."

A block of code is set as follows:

url = 'http://www.gutenberg.org/ebooks/1661.txt.utf-8'
file_name = 'sherlock.txt'

Any command-line input or output is written as follows:

import pandas as pd
import numpy as np

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "The Prediction: pos is actually a result from the file I uploaded to this page earlier."
