class_method和static_method 类中定义的函数有两大类(3小种)用途,一类是绑定方法,另外一类是非绑定方法 1.绑定方法: 特殊之处:绑定给谁就应该由谁来调用,谁来调用就会将谁当做第一个参数自动传入 1.1绑定给对象的:类中定义的函数默认就是绑定对象的。 1.2绑定给类的:在类中定义的函数上加上一个装饰器class...

static method static method不与类中的任何元素绑定。static method就如同在python文件中直接定义一个方法一样,不同之处只在于。同class method和instance method不同的是,static method不接收任何隐式传入的参数(比如class method的cls和instance method的self)。static method可以由类本身或类实例调用。
