1、@property 装饰器后面的函数,在实例调用中不能加(),不然会出现错误:TypeError: 'str' object is not callable 2、正常的方法,在实例调用中如果不加() ,就是不运行函数,而只是返回函数(方法)的地址:> 3、@staticmethod 装饰器后面的函数,在实例调用中必须加对像参数,不然会提示:TypeError: statictime() ta...

It is callable without instantiating the class first. It’s definition is immutable via inheritance. Python does not have to instantiate a bound-method for object. It eases the readability of the code: seeing @staticmethod, we know that the method does not depend on the state of object ...
