Metaprogramming in Python is a powerful programming technique that allows developers to write code that manipulates or generates other code. This dynamic capability enables the creation of flexible and reusable solutions, enhancing the efficiency of software development. In Python, metaprogramming can be achieved through various constructs such as decorators, metaclasses, and dynamic code generation. These tools allow programmers to modify the behavior of functions and classes at runtime, leading to more expressive and adaptable code. While metaprogramming offers significant advantages, it also requires careful handling to avoid complexity and maintain code readability.
