Metaprogramming with Python

By: Sulekha AloorRavi

Overview of this book

Effective and reusable code makes your application development process seamless and easily maintainable. With Python, you will have access to advanced metaprogramming features that you can use to build high-performing applications. The book starts by introducing you to the need and applications of metaprogramming, before navigating the fundamentals of object-oriented programming. Next, you will learn about simple decorators, work with metaclasses, and later focus on introspection and reflection. You’ll also delve into generics and typing before defining templates for algorithms. As you progress, you will understand your code using abstract syntax trees and explore method resolution order. This Python book also shows you how to create your own dynamic objects before structuring the objects through design patterns. Finally, you will learn simple code-generation techniques along with discovering best practices and eventually building your own applications. By the end of this learning journey, you’ll have acquired the skills and confidence you need to design and build reusable high-performing applications that can solve real-world problems.

Summary

In this chapter, we have learned how to create simple decorators and how to apply decorators with examples. We saw how to exchange decorators from one function to another along with how to add multiple decorators to one function.

We now understand the concept of class decorators and have looked at an example of how to apply them. And finally, we learned how to use some built-in decorators such as @staticmethod and @classmethod.

All of these concepts are part of Python metaprogramming and they are used to change the behavior of a function or a method externally and without impacting the internal functionalities of the function or method.

In the next chapter, we will be looking at the concept of meta classes with different examples.
