I study network programming and would like to write a simple command-line chat in Python.

I'm wondering how make receving constant along with inputing available for sending at any time.

As you see, this client can do only one job at a time:

from socket import *

HOST = 'localhost'
PORT = 21567
BUFSIZE = 1024
ADDR = (HOST, PORT)

tcpCliSock = socket(AF_INET, SOCK_STREAM)
tcpCliSock.connect(ADDR)

while 1:
    data = raw_input('> ')
    if not data: break
    tcpCliSock.send(data)
    data = tcpCliSock.recv(BUFSIZE)
    if not data: break
    print data

tcpCliSock.close()

So if another client sends a message, this client will only receive it after sending a message too. I bet you understand me. I have googled for the matter and found out many interesting things such as asynchronous I/O, threading, non-blocking synchronization, concurrent programming and so on. I have also installed the twisted package. In brief, I've been learning all these things but yet haven't found what I was looking for. (Of course, I will keep trying and trying until I get to the point.)

So, my question is how make that? =)

look into asyncore (it comes with base python)
