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 6. Creating Reusable Modules

As well as being a good technique for writing programs for your own use, modular programming is also an excellent way of writing programs that can be used by other programmers. In this chapter, we will look at how to design and implement modules and packages that can be shared and reused in other programs. In particular, we will:

  • See how modules and packages can be used as a way of sharing the code that you write

  • See how writing a module for reuse differs from writing a module for use as part of just one program

  • Discover what makes a module suitable for reuse

  • Look at examples of successful reusable modules

  • Design a package to be reusable

  • Implement a reusable package

Let's start by taking a look at how you can use modules and packages to share your code with other people.
