In Python, not only can we derive a class from the superclass but you can also derive a class from the derived class. This form of inheritance is known asmultilevel inheritance. Here's the syntax of the multilevel inheritance, classSuperClass:# Super class code hereclassDerivedClass1(Super...
在上面的例子中,我们定义了三个类A、B和C。类A和类B分别定义了方法method_a和method_b,而类C继承了类A和类B,并定义了自己的方法method_c。我们创建了一个类C的实例c,并调用了其继承自类A和类B的方法method_a和method_b,以及自己定义的方法method_c。 运行上述代码,将会得到如下输出结果: 代码语言:txt A...

In a class hierarchy with single inheritance, super can be used to refer to parent classes without naming them explicitly, thus making the code more maintainable. This use closely parallels the use of super in other programming languages. The second use case is to support cooperative multiple ...
继承是面向对象编程的一个重要方式，可以扩展父类的功能，而Python作为热门的编程语言，同样具备该功能;除...
C3 superclass linearization is an algorithm used primarily to obtain the order in which methods should be inherited in the presence of multiple inheritance. C3线性算法决定了获取祖先方法的优先顺序。 In other words, the output of C3 superclass linearization is a deterministic Method Resolution Order...
Michele Simionato 在他的“Setting Multiple Inheritance Straight”中不仅仅是批评,实际上还提出了一个解决方案:他实现了 traits,这是一种源自 Self 语言的明确形式的 mixin。Simionato 在 Python 中有一系列关于多重继承的博客文章,包括“The wonders of cooperative inheritance, or using super in Python 3”;“...
But the main advantage comes with multiple inheritance, where all sorts of fun stuff can happen. See the standard docs on super if you haven’t already. Note that the syntax changed in Python 3.0: you can just say super().__init__() instead of super(ChildB, self).__init__() ...
29 super init super() lets you avoid referring to the base class explicitly, which can be nice. But the main advantage comes with multiple inheritance, where all sorts of fun stuff can happen. See the standard docs on super if you haven't already. Note that the syntax changed in Python...
④ 第四次调用的是`super.pong()`它同样是通过`mro`找到了B.pong。⑤ 第五次调用的是`C.pong(self)`,它忽略了`mro`找到是C.pong。 The MRO takes into account not only the inheritance graph but also the order in which superclasses are listed in a subclass declaration. In other words, if ...
