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 7. Advanced Module Techniques

In this chapter, we will look at a number of more advanced techniques for working with modules and packages. In particular, we will:

  • Examine the more unusual ways in which the import statement can be used, including optional imports, local imports, and how to tweak the way importing works by changing sys.path

  • Briefly examine a number of "gotchas" relating to importing modules and packages

  • Take a look at how you can use the Python interactive interpreter to help develop your modules and packages more quickly

  • Learn how to work with global variables within a module or package

  • See how to configure a package

  • Discover how to include data files as part of your Python package.
