I could send you the chat program they wrote if it would help.
It has 2 threads, listener and sender.
Might spoil your fun.
However it is very primitive and asynchronous and needs work.
Oh heck, here it is.
DO NOT PEEK BEYOND THIS POINT IF YOU WISH TO SOLVE YOURSELF.
# chat1.py
# remote unknown, firewall allow UDP 12101
import os
from threading import *
from socket import *
HOST = ''
BUFSIZE = 1024
ListenPort = 12101
ListenAddr = (HOST,ListenPort)
listenersocket = socket(AF_INET,SOCK_DGRAM)
listenersocket.bind(ListenAddr)
sendsocket = socket(AF_INET,SOCK_DGRAM)
sendsocket = socket(AF_INET,SOCK_DGRAM)
def listener():
while 1:
msg,addr = listenersocket.recvfrom(BUFSIZE)
print '<',msg
if msg == 'die-now': break
def sender():
print; print
print 'Type away. When you are thru with your'
print ' message, hit enter an extra time'
print ' to let the other guy know its his turn.'
print 'To exit, enter exit'
print; print
while 1:
msg = raw_input()
if msg == 'exit':
sendsocket.sendto( 'die-now', ('localhost',ListenPort) )
break
sendsocket.sendto( msg, (sendtoip,ListenPort) )
# Main program start here
print
sendtoip = raw_input('Enter IP address of other computer: ')
sendtoip = sendtoip.strip()
# Define and start 2 threads
listnr = Thread(target=listener)
sendr = Thread(target=sender)
listnr.start()
sendr.start()
listnr.join()
sendr.join()
