python 第一课，获取信息

#!/usr/bin/env python

import socket

print "Creating socket----",

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

print "done"

print "Looking up port number----",

port = socket.getservbyname('http','tcp')

print "done"

print "Connecting to remote host on port %d..." % port,

s.connect(("www.google.com",port))

print "done."

print "Connected from",s.getsockname()
print "Connected to",s.getpeername()

编译后输出：

Creating socket---- done

Looking up port number---- done

Connecting to remote host on port 80... done.

Connected from ('192.168.1.101', 52624)

Connected to ('173.194.127.180', 80)
