In Python, super() has two major use cases: Allows us to avoid using the base class name explicitly Working with Multiple Inheritance Example 1: super() with Single Inheritance In the case of single inheritance, we use super() to refer to the base class. class Mammal(object): def __ini...
它的多继承顺序是依据一个叫做**Method Resolution Order (MRO)**的算法来决定的,通过使用类名.mro()可以得到继承关系的顺序。 参考Python Multiple Inheritance中的一个例子 如下图所示是一个比较复杂的继承关系图 其代码编写如下 # Demonstration of MRO class X: pass class Y:...
In Class2In Class3In Class1 看出区别了吗,区别就在于super中的第一个参数。python的多继承通常来说是按顺序继承的,但也不尽然! 它的多继承顺序是依据一个叫做**Method Resolution Order (MRO)**的算法来决定的,通过使用类名.mro()可以得到继承关系的顺序。 参考Python Multiple Inheritance中的一个例子 如下...
The second use case is to support cooperative multiple inheritance in a dynamic execution environment. This use case is unique to Python and is not found in statically compiled languages or languages that only support single inheritance. This makes it possible to implement “diamond diagrams” where...

**Python Super的用法** **一、基本用法** 1. In Python, `super()` is mainly used in class inheritance. It allows you to call methods from a superclass. For example, if you have a subclass that overrides a method from its superclass, you can still use the superclass method implementati...
Note thatsuper()is implemented as part of the binding process for explicit dotted attribute lookups such assuper().__getitem__(name). It does so by implementing its own__getattribute__()method for searching classes in a predictable order that supports cooperative multiple inheritance. Accordingly...
