To Get the Most out of This Book

The software in this book is tested on Python version 3.5 and on Ubuntu version 16.04. However, majority of the examples can also be run on the Windows and Mac OS X operating systems. Also, it is useful to know about advanced syntax and new syntax introduced in the Python 3 releases. You might also want to learn about idiomatic Python programming, by checkout out resources on Internet about the topic, if needed. 

The recommended way to install Python and the associated libraries is through the Anaconda distribution, which can be downloaded from https://www.continuum.io/downloads, for Linux, Windows, and Mac OS X. Chapters in this book might discuss the use of external libraries or tools that have to be installed via a package manager such as pip and Anaconda, and specific instructions on how to install those libraries are included in their corresponding chapters.

Additionally, make sure you have installed SQLite 3.22.0 or later from https://www.sqlite.org/download.htmland RabbitMQ 3.7.7 from https://www.rabbitmq.com/download.html.

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: "In the Musician class, the main action is performed by the play() method."

A block of code is set as follows:

class Musician:
     def __init__(self, name):
         self.name = name
  
     def __str__(self):
 return f'the musician {self.name}'
  
     def play(self):
         return 'plays music'

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: "A remote proxy, which acts as the local representation of an object that really exists in a different address space (for example, a network server)."
