Abstract classes can be combined through multiple inheritance to create classes that implement multiple interfaces. TheReadWriteFileclass inherits from bothReadableandWritableabstract classes and implements all their abstract methods. This approach allows for flexible interface definitions while maintaining strict...
Like classes, interfaces define methods. Unlike classes, these methods are abstract. An abstract method is one that the interface simply defines. It doesn’t implement the methods. This is done by classes, which then implement the interface and give concrete meaning to the interface’s abstract ...
clients 不应该被强迫依赖它们用不上的方法。Interfaces 属于clients,而不是 hierarchy (层次结构)。 在这个情景里,clients 指的是类和子类,而 interfaces 包括了方法和属性。换句话说,如果一个类用不上某些方法或属性,那么这些方法和属性就该拆分到更多专门的类里。 考虑下面这个类的 hierarchy (层次结构),用于模仿...

①](#co_interfaces__protocols__and_abcs_CO14-1)定义实现它的类时,不需要导入静态协议。这里我只导入RandomPicker是为了稍后在test_isinstance中使用它。②](#co_interfaces__protocols__and_abcs_CO14-2)SimplePicker实现了RandomPicker——但它并没有继承它。这就是静态鸭子类型的作用。
The Java / C# way of using interfaces is not available here. In the dynamic language world, things are more implicit. We’re more focused on how an object behaves, rather than it’s type/class. PEP 3119 -- Introducing Abstract Base Classes | Python.org https://www.python.org/dev/...
