初学python：网络通信

    简单C/S模型，实现两主机通过socke通信。

    服务器端：

ser.py

from socket import *
import thread

PORT=5648
BUFSIZE=1024

def th():
	while True:
		data=raw_input("")
		if not data:
			break
		tcpCliSock.send(data)
ADDR=("",PORT)
tcpSerSock=socket(AF_INET,SOCK_STREAM)
tcpSerSock.bind(ADDR)
tcpSerSock.listen(5)
print "waiting fot connection..."
tcpCliSock,addr=tcpSerSock.accept()
print "connection from :%s" % str(addr)
thread.start_new_thread(th,())
while True:
	data=tcpCliSock.recv(BUFSIZE)
	if not data:
		break
	print data
tcpSerSock.close()

    客户端：

cli.py

from socket import *
import thread

HOST='localhost'
PORT=5648
BUFSIZE=1024
ADDR=(HOST,PORT)
def th(sock):
	while True:
		data=raw_input("")
		if not data:
			break
		sock.send(data)

tcpCliSock=socket(AF_INET,SOCK_STREAM)
tcpCliSock.connect(ADDR)

thread.start_new_thread(th,(tcpCliSock,))
while True:
	data=tcpCliSock.recv(BUFSIZE)
	print data
tcpCliSock.close()
