class method & static method 类的装饰器函数

　　

class Mse:
　　 @classmethod
　　def __new__(cls,*args,**kwargs):
　　　　pass
    @classmethod
    def class_method(cls):
        print('class={0.__name__} ({0})'.format(cls))
        cls.HEIGHT=88
    @staticmethod
    def static_method():
        print(Mse.HEIGHT)
Mse.class_method()　　
Mse.static_method()
print(Mse.__dict__)

 

def setnameproperty(name):
    def wrapper(cls):
        cls.NAME=name
        return cls
    return wrapper
@setnameproperty('vbn')
class MyXiv:
    pass
print(MyXiv.NAME)
print(MyXiv.__dict__)

MyXiv仍然指向同一内存地址

MyXiv=wrapper(MyXiv)
