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.

In this chapter, we looked at the concept of a reusable module or package. We saw how reusable packages and modules can be used to share code with other people. We learned that a reusable module or package needs to function as a standalone unit, should ideally use relative imports, and should note any external dependencies it may have. Ideally, a reusable package or module will also solve a general problem rather than a specific one, follow standard Python coding conventions, and have good documentation. We then looked at some examples of good reusable modules, before writing one of our own.

In the next chapter, we will look at some of the more advanced aspects of working with modules and packages in Python.
