Overview of this book

Python is the preferred choice of developers, engineers, data scientists, and hobbyists everywhere. It is a great language that can power your applications and provide great speed, safety, and scalability. It can be used for simple scripting or sophisticated web applications. By exposing Python as a series of simple recipes, this book gives you insight into specific language features in a particular context. Having a tangible context helps make the language or a given standard library feature easier to understand. This book comes with 133 recipes on the latest version of Python 3.8. The recipes will benefit everyone, from beginners just starting out with Python to experts. You'll not only learn Python programming concepts but also how to build complex applications. The recipes will touch upon all necessary Python concepts related to data structures, object oriented programming, functional programming, and statistical programming. You will get acquainted with the nuances of Python syntax and how to effectively take advantage of it. By the end of this Python book, you will be equipped with knowledge of testing, web services, configuration, and application integration tips and tricks. You will be armed with the knowledge of how to create applications with flexible logging, powerful configuration, command-line options, automated unit tests, and good documentation.

Using a class to encapsulate data and processing

Class design is influenced by the SOLID design principles. The Single Responsibility and Interface Segregation principles offer helpful advice. Taken together, these principles advise us that a class should have methods narrowly focused on a single, well-defined responsibility.

Another way of considering a class is as a group of closely-related functions working with common data. We call these methods for working with the data. A class definition should contain the smallest collection of methods for working with the object's data.

We'd like to create class definitions based on a narrow allocation of responsibilities. How can we define responsibilities effectively? What's a good way to design a class?

Getting ready

Let's look at a simple, stateful object—a pair of dice. The context for this is an application that simulates a simple game like Craps. This simulation can help measure the house...
