我在方法装饰器和类装饰器方面遇到了问题。

def log_decorator(func):
    def wrapper(*args, **kwargs):
        print("Calling function:", func.__name__)
        result = func(*args, **kwargs)
        print("Function", func.__name__, "finished execution")
        return result
    return wrapper

class MyClass:
    @log_decorator
    def my_method(self):
        print("Executing my_method")

obj = MyClass()
obj.my_method()

Calling function: my_method
Executing my_method
Function my_method finished execution

def add_property(cls):
    cls.new_property = "New Property"
    return cls

@add_property
class MyClass:
    pass

obj = MyClass()
print(obj.new_property)

New Property
