Summary
In this chapter, we provide a quick overview of the programming paradigm of metaprogramming and looked at an example of solving a type error using metaprogramming in Python 3.
We learned why there is a need to apply metaprogramming techniques in the Python application development process. We also learned about the Don’t Repeat Yourself concept by looking at a practical approach that explains an example implementation of dynamic function creation using metaprogramming, emphasizing the concepts of avoiding repetition and implementing abstraction at the meta level in the code. Finally, we provided a high-level overview of the applications of metaprogramming that we will look at throughout this book. These skills will help us understand how and why to apply metaprogramming in various applications.
In the next chapter, we will review the object-oriented programming concepts of Python. The next chapter is more of a refresher on object-oriented programming concepts and is optional if you are already familiar with those concepts.
