python的socket基本使用

server.py: 

import socket

s = 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 socket

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