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 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)
