用python做socket程式設計，從實現上來講，是非常簡單的。下面是從他的幫助文件裡面取出來的兩段**，顯示了服務端和客戶端。
服務端:
# echo server program
import socket
host =
'127.0.0.1' # symbolic name meaning the local host
port = 50007 # arbitrary non- privileged port
s = socket. socket( socket. af_inet, socket. sock_stream)
s. bind(
( host, port)
)s. listen( 1)
conn, addr = s. accept(
'connected by'
, addr
while 1:
data = conn. recv( 1024)
ifnot data:
break
conn. send( data)
conn. close(
)
客戶端:
# echo client program
import socket
host =
'127.0.0.1' # the remote host
port = 50007 # the same port as used by the server
s = socket. socket( socket. af_inet, socket. sock_stream)
s. connect(
( host, port)
)s. send(
'hello, world'
)data = s. recv( 1024)
s. close(
'received'
, repr( data)
很簡單的**，在服務端啟動程式後，進入訊息等待迴圈。當客戶端連線後並傳送訊息，而在服務端收到訊息後，傳送訊息，並在客戶端及服務端關閉socket.
