Python开发接口

Python本身不提供Interface的创建和使用

安装zope.interface

pip install zope.interface

 

 

interface_demo.py

 

 代码：

from zope.interface import Interface
from zope.interface.declarations import implementer

#定义接口
class IHost(Interface):
    def sayHello(self, host):
        """Say Hello to host"""

@implementer(IHost)  #继承接口
class Host:
    def sayHello(self, guest):
        return "Hi %s:" % guest

if __name__ == '__main__':
    host1 = Host()
    hello = host1.sayHello('Jake')
    print(hello)
