python的socket基本使用

server.py: 

import sockets = socket.socket(socket.AF_INET, socket.SOCK_STREAM)s.bind(('127.0.0.1', 5000))s.listen(1)while True:    cs, ca = s.accept()    print cs.recv(1024)    cs.sendall('reply')    cs.close()

client.py:

import socketc = socket.socket(socket.AF_INET, socket.SOCK_STREAM)c.connect(('127.0.0.1', 5000))c.send('hello')print c.recv(1024)c.close()
