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: "Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system."

A block of code is set as follows:

class Point: def __init__(self, x=0, y=0): self.move(x, y) 

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 database 
db = database.Database() 
# Do queries on db 

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

>>> print(secret_string._SecretString__plain_string)
ACME: Top Secret ...
