类装饰器

class Decorator:
    def __init__(self, func):
        self.func = func

    def __call__(self, *args, **kwargs):
        print('-----call-----')
        return self.func(*args, **kwargs)


@Decorator
class MyClass:
    pass

@Decorator
class MyClass1:
    def __init__(self,name):
        self.name = name


print(type(MyClass()))

print(MyClass1("haha").name)

打印结果：

-----call-----

-----call-----
haha
