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.

Using pip to download and install modules and packages

In chapters 4 and 5 of this book, we used pip, the Python Package Manager, to install various libraries that we wanted to work with. As we learned in Chapter 7, Advanced Module Techniques, pip normally installs a package into Python's site-packages directory. Since this directory is listed in the module search path, your newly installed module or package can then be imported and used in your code.

Let's now use pip to install the test package we created in the previous section. Since we know that our package has been given the name <username>_test_package, where <username> is your GitHub username, you can install this package directly into your site-packages directory by typing the following command into a terminal or command-line window:

pip install <username>_test_package

Make sure you replace <username> with your GitHub username. Note that if you do not have permission to write to your Python installation's site...
