A brief discussion of the definition of interfaces, abstract classes and abstract methods in Python
#_*_ coding:utf-8 _*_ #知识点:接口的定义和抽象类以及抽象方法 ''' 1、抽象类式啥? 抽象类加上抽象方法就等于接口 2、接口的定义 含义1、别人给你暴露一个URL,然后调用这个URL 含义2、定义一个规范,不写具体实现,按照这个规范去实现相关功能,抽象类就是属于这种 ''' from abc import ABCMeta, abstractmethod #定义一个抽象类 class Alert: __metaclass__ = ABCMeta @abstractmethod def Send(self):pass #抽象方法 class Foo(Alert): #继承抽象类(或者说继承接口),就得按照抽象类的规范 def __init__(self): print '__init__' def Send(self): #抽象类里有send方法,所以,在这里也必须要有send方法 print 'send.Weixin' f = Foo() f.Send()
