You can take a look at this. Basically, it should be something like (note that the sample handling is just an example, you will have to do something better):
import threading
import socket
def print_message(socket):
data = socket.recv(512)
print(data)
def handle_client(clientsocket):
print("We have a new client")
thread = threading.Thread(target=print_message, args=(clientsocket,))
thread.run()
# create an INET, STREAMing socket
serversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# bind the socket to a public host, and a well-known port
serversocket.bind((socket.gethostname(), 8080))
# become a server socket
serversocket.listen(5)
while True:
# accept connections from outside
(clientsocket, address) = serversocket.accept()
# now do something with the clientsocket
# in this case, we'll pretend this is a threaded server
ct = handle_client(clientsocket)

Ehi thanks man the code work fine but the threading is the best/only method?because i read that threading performs poorly in python is right? – user3782573 Jul 18 '14 at 10:20

I have read somewhere that some Python implementations don't have good threading performance for CPU-bound tasks. Your case seems like IO-bound task, however, so I think that there is no problem to use threads. Furthermore, you can not achieve multiple clients server, without threads or processes (which I believe won't perform better). The problem is that before you can accept a new client, you need to invoke `serversocket.accept()`, which in single-threaded application will happen after `handle_client` is completed. – Ivaylo Petrov Jul 18 '14 at 15:04
