Python implements a simple instance of interprocess communication _python

This article illustrates how Python implements communication between two programs, in the following ways:

This example uses socket realization, and socket network programming is not the same as Socket.socket (Socket.af_unix, socket. SOCK_STREAM) is the first parameter of the Socket.af_unix
And not socket.af_inet.
Example of two Python program s.py/c.py to run first s.py
Based on fedora13/python2.6 test, successful implementation!

The s.py code is as follows:

#!/usr/bin/env python
Import socket
import OS

if __name__ = = ' __main__ ':
  sock = socket.socket (socket. Af_unix, Socket. SOCK_STREAM)
  conn = '/tmp/conn '
  if not os.path.exists (conn):
  Os.mknod (conn)
  if os.path.exists (conn) :
  Os.unlink (conn)
  Sock.bind (conn)
  Sock.listen (5) while
  True:
  connection,address = Sock.accept ()
  data = CONNECTION.RECV (1024)
  if data = "Hello,server":
    print "The client said:%s!\n"% Data
      connection.send ("hello,client")
  Connection.close () 

The c.py code is as follows:

 #!/usr/bin/env python import socket import time if __name__ = ' __main__ ': sock = Socke T.socket (Socket.af_unix, socket. 
  SOCK_STREAM) conn = '/tmp/conn ' sock.connect (conn) time.sleep (1) sock.send (' Hello,server ') print SOCK.RECV (1024) Sock.close ()
