把內容過程中經常用的一些內容備份一次，下面內容是關於python通過socket獲得點對點的信息的內容。

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,
print "done."

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

返回結果如下：

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)
