本文实例讲述了Python+Socket实现基于UDP协议的局域网广播功能。分享给大家供大家参考，具体如下：

服务器端：

# udp_gb_server.py'''服务端（UDP协议局域网广播）'''import sockets = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)s.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)PORT = 1060network = '<broadcast>'s.sendto('Client broadcast message!'.encode('utf-8'), (network, PORT))

客户端：

# udp_gb_client.py'''客户端（UDP协议局域网广播）'''import sockets = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)s.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)PORT = 1060s.bind(('', PORT))print('Listening for broadcast at ', s.getsockname())while True:  data, address = s.recvfrom(65535)  print('Server received from {}:{}'.format(address, data.decode('utf-8')))

运行效果：
