Write a decorator in python.

Question

Accepted Answer

A decorator in Python is a design pattern that allows you to add new functionality to an existing object without modifying its structure.

Decorators are functions that take another function as an argument and extend its behavior without modifying it directly.
They are commonly used to add logging, timing, or authentication to functions.
Syntax: @decorator_function above the function definition.
Example: def my_decorator(func): def wrapper(): print('Something is happening before the function is called.') func() print('Something is happening after the function is called.') return wrapper @my_decorator def say_hello(): print('Hello!') say_hello()
Output: Something is happening before the function is called. Hello! Something is happening after the function is called.
