本文實例講解了python實現兩個程序之間通信的方法，具體方法如下：

該實例采用socket實現，與socket網絡編程不一樣的是socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)的第一個參數是socket.AF_UNIX
而不是 socket.AF_INET
例中兩個python程序 s.py/c.py 要先運行s.py
基于fedora13/python2.6測試，成功實現！

s.py代碼如下：

#!/usr/bin/env pythonimport socketimport osif __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() 

c.py代碼如下：

#!/usr/bin/env pythonimport socketimport timeif __name__ == '__main__':  sock = socket.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()
