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.

The process of programming

All too often as programmers, we focus on the technical details of a program. That is, we focus on the product rather than the process of programming. The difficulties of solving a particular programming problem are so great that we forget that the problem itself will change over time. No matter how much we try to avoid it, change is inevitable: changing markets, changing requirements, and changing technologies. As programmers, we need to be able to effectively cope with this change just as much as we need to be able to implement, test, and debug our code.

Back in Chapter 4, Using Modules for Real-World Programming, we looked at an example program that faced the challenge of changing requirements. We saw how a modular design allowed us to minimize the amount of code that had to be rewritten when the scope of the program increased well beyond what was first envisaged.

Now that we have learned more about modular programming and the related technologies that can help...
