Summary
In this chapter, we learned the concept of classes and objects in Python and we also discussed how to build classes and use them to create objects and instances. Later, we deep-dived into the four pillars of OOP: encapsulation, inheritance, polymorphism, and abstraction. We also worked through simple and clear code examples to make it easier for readers to grasp the concepts of OOP. These four pillars are fundamental to using OOP in Python.
In the later sections, we also covered duck typing, which is important for clarifying its non-dependency on classes, before ending the chapter by reviewing when it is not significantly beneficial to use OOP.
By going through this chapter, you not only refreshed your knowledge of the main concepts of OOP but also learned how to apply the concepts using Python syntax. We will review a few Python libraries for advanced programming in the next chapter.
