Python problem Ping

python By calling ping command , Judge liansuodian LAN in the list ip Whether the address is connected , If it works , Get delay information 、 Packet loss information 、 Average delay and other related return information , And by judging the delay time , The delay time exceeds 10 Second warning , Take out the negative alert information and give it a list value . If it doesn't work, it doesn't work ip Address , Pay an address to a list . every other 10 The automatic cycle is executed every minute .
I wrote it now , If more than one doesn't work , Only the first one can extract ip Address , Then it jumps out of the loop , How can I write it to meet the needs I put forward above . Please point out. thank you , Be deeply grateful
