python attribute decorator

To create a decorator in python is really easy. If you apply hello_world_decorator to say any method, it will execute the wrapper first.

def hello_world_decorator(func):

    def wrapper(*args, **kwargs):

        print("Hello, world")

        return func(*args, **kwargs)

    return wrapper

class Employee(BaseModel):

    name: str

    id: int

    @hello_world_decorator

    def hello(_self):

     print("emplyoee")

 So you will get the following output

Hello, world

employee
