Python 3 Object Oriented Programming

By: Dusty Phillips

Overview of this book

Object Oriented Programming is a very important aspect of modern programming languages. The basic principles of Object Oriented Programming are relatively easy to learn. Putting them together into working designs can be challenging.This book makes programming more of a pleasure than a chore using powerful Python 3 object-oriented features of Python 3. It clearly demonstrates the core OOP principles and how to correctly implement OOP in Python. Object Oriented Programming ranks high in importance among the many models Python supports. Yet, many programmers never bother learning the powerful features that make this language object oriented.The book teaches when and how OOP should be correctly applied. It emphasizes not only the simple syntax of OOP in Python, but also how to combine these objects into well-designed software.This book will introduce you to the terminology of the object-oriented paradigm, focusing on object-oriented design with step-by-step examples. It will take you from simple inheritance, one of the most useful tools in the object-oriented programmer's toolbox, all the way through to cooperative inheritance, one of the most complicated. You will be able to raise, handle, define, and manipulate exceptions.You will be able to integrate the object-oriented and the not-so-object-oriented aspects of Python. You will also be able to create maintainable applications by studying higher level design patterns. You'll learn the complexities of string and file manipulation, and how Python distinguishes between binary and textual data. Not one, but two very powerful automated testing systems will be introduced to you. You'll understand the joy of unit testing and just how easy they are to create. You'll even study higher level libraries such as database connectors and GUI toolkits and how they apply object-oriented principles.

Case study


Let's try to tie everything we've learned together with a larger example. We'll be designing a simple real estate application that allows an agent to manage properties available for purchase or rent. There will be two types of properties: apartments and houses. The agent needs to be able to enter a few relevant details about new properties, list all currently available properties, and mark a property as sold or rented. For brevity, we won't worry about editing property details or reactivating a property after it is sold.

The project will allow the agent to interact with the objects using the Python interpreter prompt. In this world of graphical user interfaces and web applications, you might be wondering why we're creating such old-fashioned looking programs. Simply put, both windowed programs and web applications require a lot of overhead knowledge and boilerplate code to make them do what is required. If we were developing software using either of these paradigms, we'd get so...
