Socket client and server in Python

A sample example for connection server and client use socket in Python

Client.py

import socket 
s=socket.socket(socket.AF_INET,socket.SOCK_STREAM) 
s.connect(('localhost',8081)) 
s.send('Happy hacking') 
data=s.recv(1024) 
s.close() 
print "Received:" 
print data

Server.py

import socket 
import sys 

#Create a TCP/IP socket to listen on 
server=socket.socket(socket.AF_INET,socket.SOCK_STREAM)  

#Prevent from "address already in use" upon server restart 
server.setsockopt(socket.SOL_SOCKET,socket.SO_REUSERADDR,1)  
#Bind the socket to port 8081 on all interfaces 
server_address=('localhost',8081) 
print  'starting up on %s port %s' % server_address 
server.bind(server_address)  

#Listen for connections 
server.listen(5)  

#Wait for one incomming connection 
connection,client_address=server.accept() 
print 'connection from ', connection.getpeername()  

#Let's receive something 
data=connection.recv(4096) 
if data: 
    print "received ", repr(data)
     #send it back nicely formatted
     data=data.rstrip()
     connection.send('%s\n%s\n%s\n' % ('-'*80,data.center(80),'-'*80))
     print "Response sent!"
#close the connection from our side 
connection.shutdown(socket.SHUT_RD | socket.SHUT_WR) 
connection.close() 
print "Connection closed."  

#Aa and stop listening 
server.close()
