那就用abstract class来模拟interface定义吧! 呵呵, python好像连abstract class也不是原生态的, 好在还有一个ABC(abstract base class), 将就用吧. abstract base class http://3.1.onlypython.appspot.com/post/3521/ 下面是一个例子: 代码 Square类一定要实现draw()方法, 否则, 当实例化一个Square...
abstract class 和 interface区别 相同点: 1.都不能被直接实例化,都可以通过继承实现其抽象方法; 不同点: 1.接口支持多继承,抽象类只能由一个父类; 2.接口只能定义行为,抽象类既可以定义行为,又可以提供实现; 3.接口只包含方法、属性、索引器、事件的签名,但不能定义字段和包含实现的方法;抽象类可以; 4....

Python 并不直接支持接口(Interface)这一概念,而是通过抽象基类(Abstract Base Class, ABC)来实现类似接口的功能。Python 的设计哲学强调简洁性和灵活性,因此引入了抽象基类而非传统的接口。抽象基类提供了一种方式来定义接口,允许开发者指定必需的方法和属性,而具体实现则留给子类。尽管抽象基类和接口在功能上有相似之...

Understanding the differences between an abstract class and interface is key to designing loosely coupled and extensible applications.

Do I mean Python the abstractinterface? Do I mean CPython, the common Pythonimplementation(and not to be confused with the similarly named Cython)? Or do I mean something else entirely? Maybe I’m obliquely referring to Jython, or IronPython, or PyPy. Or maybe I’ve really gone off the...
