    python的twisted比较有意思，既可以做server方面的编程，也可以做client方面的编程。关于这方面的编程，最简单的例子就是echo。

    client 代码如下，

#!/usr/bin/python

from twisted.internet.protocol import Protocol, ClientFactory
from sys import stdout
from twisted.internet import reactor

class Echo(Protocol):
	def dataReceived(self, data):
		stdout.write(data)
 
class EchoClientFactory(ClientFactory):
	def startedConnecting(self, connector):
		print ‘Started to connect.‘
   
	def buildProtocol(self, addr):
		print ‘Connected.‘
		return Echo()
   
	def clientConnectionLost(self, connector, reason):
		print ‘Lost connection. Reason:‘, reason
	
	def clientConnectionFailed(self, connector, reason):
		print ‘Connection failed. Reason:‘, reason

if __name__ == ‘__main__‘:
	reactor.connectTCP(‘localhost‘, 1234, EchoClientFactory())
	reactor.run()

#!/usr/bin/python

from twisted.internet.protocol import Protocol, ClientFactory
from sys import stdout
from twisted.internet import reactor

class Echo(Protocol):
	def dataReceived(self, data):
		stdout.write(data)
 
class EchoClientFactory(ClientFactory):
	def startedConnecting(self, connector):
		print ‘Started to connect.‘
   
	def buildProtocol(self, addr):
		print ‘Connected.‘
		return Echo()
   
	def clientConnectionLost(self, connector, reason):
		print ‘Lost connection. Reason:‘, reason
	
	def clientConnectionFailed(self, connector, reason):
		print ‘Connection failed. Reason:‘, reason

if __name__ == ‘__main__‘:
	reactor.connectTCP(‘localhost‘, 1234, EchoClientFactory())
	reactor.run()
