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。
