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 multiple base classes implement the same method. Good design dictates that this method have the same...
In Python,super()has two major use cases: Allows us to avoid using the base class name explicitly Working withMultiple Inheritance Example 1: super() with Single Inheritance In the case of singleinheritance, we usesuper()to refer to the base class. classMammal(object):def__init__(self, m...
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...

In 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 ...
python也具有多继承的功能,而同样的,大家能想到多继承必须要引入一些特定的方法来准确调用子类或基类的重载、重写的方法,否则会出现混乱。 本文参考Multiple inheritance in Python对该问题进行简要论述。 如下图描述了一个简单的类继承关系
**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...

在Python 3 中,我们可以这样称呼它: class ChildB(Base): def __init__(self): super().__init__() 在Python 2 中,我们需要调用 super 像这样使用定义类的名称和 self ,但从现在开始我们将避免这种情况,因为它是多余的,速度较慢(由于名称查找),以及更冗长的内容(如果您还没有更新 Python,请更新!):...
The attribute is dynamic and can change whenever the inheritance hierarchy is updated. If the second argument is omitted, the super object returned is unbound. If the second argument is an object, isinstance(obj, type) must be true. If the second argument is a type, issubclass(type2, type...
