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.

Combining many applications using the Command Design Pattern

Many complex suites of applications follow a design pattern similar to the one used by the Git program. There's a base command, git, with a number of subcommands. For example, git pull, git commit, and git push.

What's central to this design is the idea of a collection of individual commands under a common parent command. Each of the various features of Git can be thought of as a separate class definition that performs a given function.

In this recipe, we'll see how we can create families of closely related commands.

Getting ready

We'll imagine an application built from three commands. This is based on the applications shown in the Designing scripts for composition and Using logging for control and audit output recipes in Chapter 13, Application Integration: Configuration, as well as the Combining two applications into one recipe from earlier in this chapter. We'll have three applications...
