    def __init__(self,host,port):
        self.ip = host
        self.port = port

    def start(self):
        print("start server..")

    def stop(self):
        print("stop server..")

    def restart(self):
        self.stop()
        self.start()

if __name__ == ‘__main__‘:
    server = WebServer("localhost",333)
    if hasattr(server,sys.argv[1]):
        func = getattr(server,sys.argv[1])
        func()

2.setattr

#!/usr/bin/env python
#-*- coding:utf-8 –*-
import sys

class WebServer(object):
    def __init__(self,host,port):
        self.ip = host
        self.port = port

def test_run(name):
    print("running...",name)


if __name__ == ‘__main__‘:
    server = WebServer("localhost",333)
    setattr(server,"run",test_run)
    server.run("jack")

3.delattr

import sys

class WebServer(object):
    def __init__(self,host,port):
        self.host = host
        self.port = port

    def test_run(name):
        print("running...",name)


if __name__ == ‘__main__‘:
    server = WebServer("localhost",333)
    delattr(server,‘port‘)
