python error : 'module' object has no attribute 'AF_UNIX'

Question

this is my python code :

if __name__ == '__main__':  
    import socket  
    sock = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)  
    sock.connect(('0.0.0.0', 4000))  
    import time  
    time.sleep(2)  
    #sock.send('1')
    print sock.recv(1024)  
    sock.close()  

it show :

Traceback (most recent call last):
  File "D:\Program Files\test\test\python\client.py", line 3, in <module>
    sock = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)
AttributeError: 'module' object has no attribute 'AF_UNIX'

what can i do ,

While creating a socket object on Windows you should do:

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

AF_INET for Internet addresses, and AF_UNIX for UNIX inter-process communication. The latter is obviously only available on UNIX platforms.

Also, follow this example to find how to implement a simple socket server and client.
