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: “For example, Remove_Stop_Words() relies on a list comprehension to perform the actual processing.”

A block of code is set as follows:

import getpass
user = getpass.getuser()
pwd = getpass.getpass("User Name : %s" % user)

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

import getpass
user = getpass.getuser()
pwd = getpass.getpass("User Name : %s" % user)
