Improved One way message redux using sockets.

client.py

import socket               # Import socket module

host = raw_input("Host IP: ") # Get local machine name
port = 12345                # Reserve a port for your service.

while True:
    s = socket.socket()         # Create a socket object

    s.connect((host, port))
    print s.recv(1024)
    s.close                     # Close the socket when done

server.py

import socket               # Import socket module

s = socket.socket()         # Create a socket object
host = socket.gethostname() # Get local machine name
port = 12345                # Reserve a port for your service.
s.bind((host, port))        # Bind to the port
print("Your IP is: " + str(host))
s.listen(5)                 # Now wait for client connection.
while True:
   c, addr = s.accept()     # Establish connection with client.
   print 'Got connection from', addr
   x = raw_input("Send: ")
   print("\n"*25)
   print("Your IP is: " + str(host))
   c.send(x)
   c.close()                # Close the connection
