Overview of this book

Object-oriented programming (OOP) is a popular design paradigm in which data and behaviors are encapsulated in such a way that they can be manipulated together. Python Object-Oriented Programming, Fourth Edition dives deep into the various aspects of OOP, Python as an OOP language, common and advanced design patterns, and hands-on data manipulation and testing of more complex OOP systems. These concepts are consolidated by open-ended exercises, as well as a real-world case study at the end of every chapter, newly written for this edition. All example code is now compatible with Python 3.9+ syntax and has been updated with type hints for ease of learning. Steven and Dusty provide a comprehensive, illustrative tour of important OOP concepts, such as inheritance, composition, and polymorphism, and explain how they work together with Python’s classes and data structures to facilitate good design. In addition, the book also features an in-depth look at Python’s exception handling and how functional programming intersects with OOP. Two very powerful automated testing systems, unittest and pytest, are introduced. The final chapter provides a detailed discussion of Python's concurrent programming ecosystem. By the end of the book, you will have a thorough understanding of how to think about and apply object-oriented principles using Python syntax and be able to confidently create robust and reliable programs.

Recall

Some key points in this chapter:

  • Analyzing problem requirements in an object-oriented context
  • How to draw Unified Modeling Language (UML) diagrams to communicate how the system works
  • Discussing object-oriented systems using the correct terminology and jargon
  • Understanding the distinction between class, object, attribute, and behavior
  • Some OO design techniques are used more than others. In our case study example, we focused on a few:
    • Encapsulating features into classes
    • Inheritance to extend a class with new features
    • Composition to build a class from component objects
