Modular Programming with Python

By: Erik Westra

Overview of this book

Python has evolved over the years and has become the primary choice of developers in various fields. The purpose of this book is to help readers develop readable, reliable, and maintainable programs in Python. Starting with an introduction to the concept of modules and packages, this book shows how you can use these building blocks to organize a complex program into logical parts and make sure those parts are working correctly together. Using clearly written, real-world examples, this book demonstrates how you can use modular techniques to build better programs. A number of common modular programming patterns are covered, including divide-and-conquer, abstraction, encapsulation, wrappers and extensibility. You will also learn how to test your modules and packages, how to prepare your code for sharing with other people, and how to publish your modules and packages on GitHub and the Python Package Index so that other people can use them. Finally, you will learn how to use modular design techniques to be a more effective programmer.

Chapter 1. Introducing Modular Programming

Modular programming is an essential tool for the modern developer. Gone are the days when you could just throw something together and hope that it works. To build robust systems that last, you need to understand how to organize your programs so that they can grow and evolve over time. Spaghetti coding is not an option. Modular programming techniques, and in particular the use of Python modules and packages, will give you the tools you need to succeed as a professional in the fast changing programming landscape.

In this chapter, we will:

  • Look at the fundamental aspects of modular programming

  • See how Python modules and packages can be used to organize your code

  • Discover what happens when modular programming techniques are not used

  • Learn how modular programming helps you stay on top of the development process

  • Take a look at the Python standard library as an example of modular programming

  • Create a simple program, built using modular techniques, to see how it works in practice

Let's get started by learning about modules and how they work.
