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.

Pretty user interfaces


All the examples throughout this book have been run from the command line. This is great for system administrators, Linux tinkerers, and the grandfather programmers of our times, but it doesn't allow us to write the sort of modern desktop programs that everyone is using these days. Indeed, some might argue that even desktop applications are archaic, and that web applications (which we'll discuss soon) and mobile apps are more contemporary!

The reason we haven't looked at graphical applications is that they invariably rely on design patterns that offer such a high level of abstraction over lower-level objects that it's hard to see the objects for the patterns. This isn't terribly useful for learning about object-oriented programming. But now that we know the ins and outs of the object-oriented paradigm, we can briefly discover the world of Graphical User Interfaces, or GUIs, for short.

It would be possible to design graphical interfaces from scratch, interacting with...
