What are Python Decorators and How do They Work?

Python decorators are a powerful feature that allows the modification of functions or methods without changing their actual code. They work by wrapping another function inside a decorator function, adding new behavior before or after the original function runs. This is especially useful for tasks like logging, access control, or timing execution. Decorators use the “@” symbol followed by the decorator name placed above the function definition. They help make the code cleaner, more modular, and reusable.
Learning decorators is an essential part of mastering Python in any Python Certification course.
