Simple socket client with python

I made version of client server socket program.
This example was presented in a previous post named Simple socket server with python.
The program is simple, the algorithm uses connection and some data processing input from the console.
I used the same test method as for the program created in C + +.
The program breaks the connection when the client enter: end connection
Here's the source code:

import socket
import sys

HOST = 'your-IP'
PORT = 5001             
s = None
for res in socket.getaddrinfo(HOST, PORT, socket.AF_UNSPEC, socket.SOCK_STREAM):
    af, socktype, proto, canonname, sa = res
    try:
 s = socket.socket(af, socktype, proto)
    except socket.error, msg:
 s = None
 continue
    try:
 s.connect(sa)
    except socket.error, msg:
 s.close()
 s = None
 continue
    break
if s is None:
    print 'could not open socket'
    sys.exit(1)
data=''
while data<>'end connection':
 data=raw_input()
 s.send(data)
 data = s.recv(1024)

s.close()
print 'Received', repr(data)

Simple socket server with python

It is a small example I created a server to see how it works with a client program made ​​in C + +.
I can not say that it really is a server that does not accept multiple connections.
The script worked stable sending manually entered text.
I not checked the stability for the large data streams.
It is also normal because as you see below is just one example.

import socket 
HOST = 'your-IP'
PORT = 5001
s= socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((HOST,PORT))
s.listen(1)
conn,addr=s.accept()
print 'Conectat la =',addr
while 1:
 data = conn.recv(1024)
 if not data : 
  break
 conn.send(data)
 print data
conn.close()

The distance between me and the server was considerable.
