Reflection in Python refers to the ability of a program to inspect and modify its own structure and behavior at runtime. This powerful feature allows developers to examine the properties of objects, classes, and modules, enabling dynamic programming techniques. With reflection, you can access attributes, methods, and even modify them on-the-fly, which can be particularly useful for debugging, testing, and building flexible applications. Python provides built-in functions such as getattr(), setattr(), and type() to facilitate reflection, making it easier to create adaptable and reusable code. Understanding reflection can significantly enhance your programming capabilities in Python.
