SOCKET CLIENT/SERVER TRÈS SIMPLE!

# Le client
# On importe socket..
from socket import *

# Variables
host = "localhost"
port = 2074
buf = 1024
addr = (host,port)

# On fait le socket
UDPSock = socket(AF_INET,SOCK_DGRAM)
def_msg = "Message?"
print "\n",def_msg

# Envois du message
while (1):
    data = raw_input('>> ')
    if not data:
        break
    else:
        if(UDPSock.sendto(data,addr)):
            print "Envois de: '",data,"' ... <ok>"

# On ferme tout
UDPSock.close()

# -------------------------
# Le serveur

# Importe socket..
from socket import *

# Variables, encore...
host = "localhost"
port = 2074
buf = 1024
addr = (host,port)

# On fait le socket
# et bind l'addresse
UDPSock = socket(AF_INET,SOCK_DGRAM)
UDPSock.bind(addr)

# On recois le message
while 1:
    data,addr = UDPSock.recvfrom(buf)
    if not data:
        print "Le client a quitte"
        break
    else:
        print "\nRecu: '",data,"'"

# On ferme tout ca
UDPSock.close()
