Decorators in Python are a powerful way to modify the behavior of functions or methods. Here’s a simple example:
def decorator_function(original_function): def wrapper_function(*args, **kwargs): print(f"Wrapper executed before {original_function.__name__}") return original_function(*args, **kwargs) return wrapper_function
@decorator_functiondef say_hello(): print("Hello!")
say_hello()Decorators can also be used with arguments:
def repeat(times): def decorator(func): def wrapper(*args, **kwargs): for _ in range(times): func(*args, **kwargs) return wrapper return decorator
@repeat(3)def greet(): print("Hi!")
greet()Decorators are widely used in Python for logging, access control, and more.
python -c "@decorator_function\ndef say_hello():\n print(\"Hello!\")\nsay_hello()"
