python基于socket实现网络广播的方法

本文实例讲述了python基于socket实现网络广播的方法。分享给大家供大家参考。具体实现方法如下：

import socket, sys

dest = ('<broadcast>', 51423)

s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

s.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST,1)

s.sendto("Hi", dest)

print "Looking for replies; press Ctrl-C to stop."

while 1:

(buf, address) = s.recvfrom(2048)

if not len(buf):

break

print "Received from %s: %s" % (address, buf)

希望本文所述对大家的Python程序设计有所帮助。
