Client

Here's simple code to send and receive data by TCP in Python:

   1 #!/usr/bin/env python
   2 
   3 import socket
   4 
   5 
   6 TCP_IP = '127.0.0.1'
   7 TCP_PORT = 5005
   8 BUFFER_SIZE = 1024
   9 MESSAGE = "Hello, World!"
  10 
  11 s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
  12 s.connect((TCP_IP, TCP_PORT))
  13 s.send(MESSAGE)
  14 data = s.recv(BUFFER_SIZE)
  15 s.close()
  16 
  17 print "received data:", data

Server

Here's simple code to serve TCP in Python:

   1 #!/usr/bin/env python
   2 
   3 import socket
   4 
   5 
   6 TCP_IP = '127.0.0.1'
   7 TCP_PORT = 5005
   8 BUFFER_SIZE = 20  # Normally 1024, but we want fast response
   9 
  10 s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
  11 s.bind((TCP_IP, TCP_PORT))
  12 s.listen(1)
  13 
  14 conn, addr = s.accept()
  15 print 'Connection address:', addr
  16 while 1:
  17     data = conn.recv(BUFFER_SIZE)
  18     if not data: break
  19     print "received data:", data
  20     conn.send(data)  # echo
  21 conn.close()
