把内容过程中经常用的一些内容备份一次，下面内容是关于python通过socket获得点对点的信息的内容。

import socketprint "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,print "done."print "Connected from", s.getsockname()print "Connected to", s.getpeername()返回结果如下：Creating socket... done.Looking up port number... done.Connecting to remote host on port 80... done.Connected from ('127.0.0.1', 51475)Connected to ('116.255.236.107', 80)
