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)
