Decorators

Decorators are functions that modify the behavior of other functions. They are often used for logging, access control, and more.

def my_decorator(func):
  def wrapper():
    print("Before the function call")
    func()
    print("After the function call")
  return wrapper

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

say_hello()

In this example, my_decorator wraps the original say_hello function with additional behavior before and after the function call.
