Software Design by Example: A Tool-Based Introduction with Python builds small versions of the things programmers use in order to give some insights into how experienced programmers think. This material can be used for self-paced study, in an undergraduate course on software design, or as an intensive workshop for programmers.

The best way to learn design in any field is to study examples, and some of the best examples of software design come from the tools programmers use in their own work. Software Design by Example: A Tool-Based Introduction with Python therefore builds small versions of the things programmers use in order to demystify them and give some insights into how experienced programmers think. From a file backup system and a testing framework to a regular expression matcher, a browser layout engine, and a very small compiler, we explore common design patterns, show how making code easier to test also makes it easier to reuse, and help readers understand how debuggers, profilers, package managers, and version control systems work so that they can use them more effectively.

This material can be used for self-paced study, in an undergraduate course on software design, or as the core of an intensive weeklong workshop for working programmers. Each chapter has a set of exercises ranging in size and difficulty from half a dozen lines to a full day's work. Readers should be familiar with the basics of modern Python, but the more advanced features of the language are explained and illustrated as they are introduced.

Features:

• Teaches software design by showing programmers how to build the tools they use every day
• Each chapter includes exercises to help readers check and deepen their understanding
• All the example code can be downloaded, re-used, and modified under an open license

Greg Wilson is a first time author aged 71, who resides in the beautiful Macedon Ranges region of central Victoria, Australia. Leaving school early, soon led to a 20 year career in the Australian Army, spent serving throughout Eastern Australia, with Active Service in Vietnam.
