Connecting client to server, python

I am having trouble with my server and client. I need the client to send information to the server, the server sends the information back, and the process repeats once more. I was able to get the client to connect to the server and have infomation sent the first round but I cant seem to figure out how to get the server to listen to client again after I shutdown the sending side using the function conn.shutdown(1). I tried connecting to the port again but I get an error that says "Transport endpoint is already connected". Any suggestions?

Try to use threads(Multithreading)-

Server App

#!/usr/bin/python           # This is server.py file

import socket               # Import socket module

s = socket.socket()         # Create a socket object
host = socket.gethostname() # Get local machine name
port = 12345                # Reserve a port for your service.
s.bind((host, port))        # Bind to the port

s.listen(5)                 # Now wait for client connection.


def clientthread(conn):
    conn.send('connected') 
    try:
        while True:        
            data = conn.recv(1024)
            processData(conn,data)
            if not data:
                break
    except Exception as ex:
        print ex
    conn.close()



while True:
   conn, addr = s.accept()    
   print 'Got connection from', addr
   thread.start_new_thread(clientthread ,(conn,))

s.close()

Client App

#!/usr/bin/python           # This is client.py file

import socket               # Import socket module

s = socket.socket()         # Create a socket object
host = socket.gethostname() # Get local machine name
port = 12345                # Reserve a port for your service.

s.connect((host, port))
print s.recv(1024)
s.close                     # Close the socket when done
