Chapter 1: The Need for and Applications of Metaprogramming
Metaprogramming with Python is a practical guide to learning metaprogramming in Python.
In today’s programming world, Python is considered one of the easiest languages to learn and use to develop useful applications. Understanding the programming concepts and applying them is easier in Python compared to any other programming language. A Python program can be written simply by adding existing libraries and making use of their inbuilt methods. At the same time, the language also has many powerful features that can help in developing robust libraries and applications.
This book covers the need for one of the most advanced features in Python, called metaprogramming, along with insights into its practical applications. Understanding the concepts of metaprogramming helps in tapping into the advanced features of Python 3 and knowing where to apply them to make Python code more reusable.
Unlike the regular Python-based application development that follows object-oriented programming, metaprogramming covers certain advanced concepts of Python that deal with manipulating the programmable objects of Python, such as its classes, methods, functions, and variables. Throughout this book, we will look at applications and examples that help in understanding these concepts in a user-friendly manner.
In this chapter, we will provide an introduction to metaprogramming and the need to perform metaprogramming using Python 3. We will cover the following topics:
- An overview of metaprogramming
- Understanding why we need metaprogramming
- Exploring the applications of metaprogramming
By the end of this chapter, you will have a high-level understanding of metaprogramming in Python 3, the need for using it, and know of a few practical examples where it can be applied.
