以上代码主要实现在局域网内A客户端发给本机端口2222的udp包转发给192.168.0.10:9999，所有192.168.0.10:9999发送回来的数据包再转发给A客户端；
为什么只会执行4条“Start the proxy..........”？不会一直循环的吗？那datas只是起一个缓冲池的作用吗？如果我要让da
>>> x=-1
>>> if x>0:
print ('11')
>>> else:
SyntaxError: invalid syntax (<pyshell#20>, line 1)
网上搜的也是：
>>> x=int(input("Please ent ......
