Preface

This book introduces the terminology of the object-oriented paradigm. It focuses on object-oriented design with step-by-step examples. It guides us from simple inheritance, one of the most useful tools in the object-oriented programmer's toolbox through exception handling to design patterns, an object-oriented way of looking at object-oriented concepts.

Along the way, we'll learn to integrate the object-oriented and not-so-object-oriented aspects of the Python programming language. We will learn the complexities of string and file manipulation, emphasizing (as Python 3 does) the difference between binary and textual data.

We'll then cover the joys of unit testing, using not one, but two unit testing frameworks. Finally, we'll explore, through Python's various concurrency paradigms, how to make objects work well together at the same time.
