Conventions used

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

Code in text: 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: “Create a histogram using the histplot method in seaborn and specify the data using the data parameter of the method.”

A block of code is set as follows:

import numpy as np
import pandas as pd
import seaborn as sns

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

data.shape
(30,2)

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

$ pip install nltk
