When Objects Are Alike

In the programming world, duplicate code is considered evil. We should not have multiple copies of the same, or similar, code in different places. When we fix a bug in one copy and fail to fix the same bug in another copy, we've caused no end of problems for ourselves.

There are many ways to merge pieces of code or objects that have a similar functionality. In this chapter, we'll be covering the most famous object-oriented principle: inheritance. As discussed in Chapter 1, Object-Oriented Design, inheritance allows us to create "is-a" relationships between two or more classes, abstracting common logic into superclasses and extending the superclass with specific details in each subclass. In particular, we'll be covering the Python syntax and principles for the following:

Basic inheritance
Inheriting from built-in types
Multiple inheritance
Polymorphism and duck typing

Working for decades in high tech has given him exposure to a lot of ideas and techniques, some bad, but most are helpful to others. Since the 1990s, Steven has been engaged with Python, crafting an array of indispensable tools and applications. His profound expertise has led him to contribute significantly to Packt Publishing, penning notable titles like "Mastering Object-Oriented," "The Modern Python Cookbook," and "Functional Python Programming." A self-proclaimed technomad, Steven's unconventional lifestyle sees him residing on a boat, often anchored along the vibrant east coast of the US. He tries to live by the words “Don't come home until you have a story.”
