Summary
In this chapter, we focused on identifying objects, especially objects that are not immediately apparent; objects that manage and control. Objects should have both data and behavior, but properties can be used to blur the distinction between the two. The DRY principle is an important indicator of code quality and inheritance and composition can be applied to reduce code duplication.
In the next chapter, we'll cover several of the built-in Python data structures and objects, focusing on their object-oriented properties and how they can be extended or adapted.
