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 2. Writing Your First Modular Program

In this chapter, we will use modular programming techniques to implement a non-trivial program. Along the way, we will:

  • Learn about the divide and conquer approach to program design

  • Examine the tasks our program needs to perform

  • Look at the information our program will need to store

  • Apply modular techniques to break our program down into individual parts

  • Figure out how each part can be implemented as a separate Python module

  • See how the various modules work together to implement our program's functionality

  • Follow this process to implement a simple but complete inventory control system

  • See how modular techniques allow you to add functionality to your program while minimizing the changes that need to be made
