Summary
In this chapter, we focused on identifying objects, especially objects that are not immediately apparent; objects that manage and control. In particular, we covered:
- Why objects should have both data and behavior
- How properties blur the distinction between data and behavior
- The DRY principle and the follies of duplicate code
- Inheritance and composition for reducing 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.
