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...

一、How methods work in Python 方法就是一个函数、以类的属性被存储。可以通过如下的形式进行声明和访问: In[1]:classPizza(object):...:def__init__(self,size):...:self.size=size...:defget_size(self):...:returnself.size...:In[2]:Pizza.get_size Out[2]:<unbound method Pizza.get_siz...
In this tutorial, you'll compare Python's instance methods, class methods, and static methods. You'll gain an understanding of when and how to use each method type to write clear and maintainable object-oriented code.

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。
