The private method and attribute can be accessed by the instance internally, so you can use the public method to access them indirectly. In deed, there is no real private method inPython, it just converts the method name to_ClassName__method_name()or_ClassName__attribute_name. You can use...

And there is a special method called the magic method. The magic method is the method that has double underscores at the beginning and end of the method name. Such as__str__,__init__, etc. The normal methods need to be called, but the magic method is called automatically when some e...

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.
那么Python为我们做了什么呢,它绑定了所有来自类_Pizza的方法以及该类的任何一个实例的方法。也就意味着现在属性get_size是Pizza的一个实例对象的绑定方法,这个方法的第一个参数就是该实例本身。 Python 1 2 3 4 >>>Pizza(42).get_size <boundmethodPizza.get_sizeof<__main__.Pizzaobjectat0x7f3138827910...

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。
