answer:To use decorators in Python, you can define a new function that takes another function as an argument, and returns a modified version of the original function. This new function can add new functionality to the original function, or modify the behavior of the original function, without requiring you to modify the original function itself. You can apply the decorator to a function by using the "@" symbol followed by the name of the decorator function immediately before the original function definition. Here is an example: ``` def my_decorator(func): def wrapper(): print("Before the function is called.") func() print("After the function is called.") return wrapper @my_decorator def say_hello(): print("Hello!") say_hello() ``` This code defines a decorator function called `my_decorator`, which takes a function as input and returns a new function called `wrapper`. The `wrapper` function adds some new functionality to the original function, in this case printing a message before and after the function is called. The `@my_decorator` syntax applies the `my_decorator` decorator to the `say_hello` function, modifying its behavior. When you run this code, it prints: ``` Before the function is called. Hello! After the function is called. ```
