A decorator is a function that modifies the behavior of another function or class without changing its code.

def decorator(func_name):
    def wrapper_fun():
        print("Before function call")
        func_name()
        print("After function call")
    return wrapper_fun

@decorator 
def say_hello():
    print("Hello!")

say_hello()

Output:

Before function call
Hello!
After function call
