Static method is similar to a class method, which can be accessed without an object. A static method is accessible to every object of a class, but methods defined in an instance are only able to be accessed by that object of a class.Static methods are not allowed to access the state of...

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。
