In this chapter, we saw decorators, discovered the reasons for having them, and a few examples using one or more at the same time. We also saw decorators that take arguments, which are usually used as decorator factories.
We scratched the surface of object-oriented programming in Python. We covered all the basics in a way that you should now be able to understand fairly easily the code that will come in future chapters. We talked about all kinds of methods and attributes that one can write in a class, we explored inheritance versus composition, method overriding, properties, operator overloading, and polymorphism.
At the end, we very briefly touched base on iterators, so now you have all the knowledge to also understand generators more deeply.
In the next chapter, we take a steep turn. It will start the second half of the book, which is much more project-oriented so, from now on, it will be less theory and more code, I hope you will enjoy following the examples and getting your hands...
