in Super.method ending Sub.method 直接调用超类的方法是这里的重点。Sub类以其专有化的版本取代了Super的方法函数。但是取代时,Sub又回调了Super所导出的版本,从而实现了默认的行为,换句话说,Sub.mothod只是扩展了Super.mothod的行为,而不是完全取代他。这种扩展编码模式常常用于构造器方法。 6、类接口技术 class S...

Here, we called the__init__()method of theMammalclass (from theDogclass) using code super().__init__('Dog') instead of Mammal.__init__(self, 'Dog') Since we do not need to specify the name of the base class when we call its members, we can easily change the base class name...
调用父类方法(Superclass Method Invocation):子类可以使用super关键字来调用父类的方法。这通常用于子类想要在覆盖方法中使用父类的实现时。 抽象类(Abstract Class):抽象类是不能被实例化的类,它定义了一组抽象的方法。抽象类可以作为父类被其他类继承,子类必须实现抽象类中的抽象方法。 接口(Interface):接口是一...
