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.

Dealing with complexity

There is no escaping the fact that computer programs are complicated. In fact, as the requirements for a package changes, this complexity only seems to increase over time—programs rarely become simpler as you go along. Modular programming techniques are an excellent way of dealing with this complexity. Through the application of modular techniques and technologies, you can:

  • Use modules and packages to keep your code well organized no matter how complicated it becomes

  • Use the standard patterns for modular design, including the divide-and-conquer technique, abstraction, and encapsulation, to keep this complexity to a minimum

  • Apply unit testing techniques to ensure that your code continues to work as it should as you change and expand the scope of your module or package

  • Write module- and function-level docstrings to clearly describe what each part of your code does so that you can keep track of everything as your program grows and changes.
