python实现socket通讯（tcp）

server:

import socket  
address = ('127.0.0.1', 31500)  
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 
s.bind(address)  
s.listen(5)  
ss, addr = s.accept()  
print 'got connected from',addr  
ss.send('byebye')  
ra = ss.recv(512)  
print ra  
ss.close()  
s.close()  



client:

import socket  
address = ('127.0.0.1', 31500)  
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)  
s.connect(address)  
data = s.recv(512)  
print 'the data received is',data  
s.send('hihi')  
s.close()
