1.hasattr和getattr
#!/usr/bin/env python
#-*- coding:utf-8 –*-
import sys
class WebServer(object):
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)
