Client example
# Echo Client in 10/30/2015 by Saitor import socket import sys # Create a TCP/IP socket sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # Connect the socket to the port where the server is listening server_address = ('localhost', 10000) print >>sys.stderr, 'connecting to %s port %s' % server_address sock.connect(server_address) try: # Send data message = 'This is the message.

Server example
