What are decorators in Python?

Decorators in Python are a powerful and useful tool that allows you to modify or extend the behavior of functions or methods in your code. They are functions that take another function as input and return a new function, typically adding some kind of functionality to the original function without modifying its source code directly.

Types of Decorators:

There are two main types of decorators in Python:

1. Function Decorators: These decorators are defined with the "@" symbol followed by the decorator function name, placed before the function definition. They can modify the behavior of the function they decorate.
2. Method Decorators: These decorators are used to modify the behavior of methods within classes. They are defined in a similar way to function decorators but are applied to methods instead.

Implementing Decorators:

To implement a decorator, you define a function that takes another function as an argument, adds some functionality, and returns a new function that includes the added behavior. You can then apply the decorator to your functions or methods by using the "@" symbol followed by the decorator's name.

Decorators are commonly used in Python programming to enhance the functionality of functions and methods without altering their original code, following the decorator pattern. They are a valuable tool for extending the behavior of your Python programs in a clean and modular way.
