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 objects, classes, and functions dynamically, enabling them to understand and manipulate code without needing to know its specifics at compile time. Python’s introspection capabilities facilitate tasks such as debugging, testing, and dynamically creating or modifying classes and functions. By leveraging reflection, programmers can write more flexible and reusable code, making it easier to adapt to changing requirements and enhancing overall productivity in software development.
