Python 执行 shell 命令添加 sudo 密码

1. ping -c 4 www.baidu.com

strong@foreverstrong:~$ ping -c 4 www.baidu.com PING www.a.shifen.com (61.135.169.121) 56(84) bytes of data. 64 bytes from 61.135.169.121: icmp_seq=1 ttl=53 time=24.8 ms 64 bytes from 61.135.169.121: icmp_seq=2 ttl=53 time=25.7 ms 64 bytes from 61.135.169.121: icmp_seq=3 ttl=53 time=25.0 ms 64 bytes from 61.135.169.121: icmp_seq=4 ttl=53 time=24.7 ms --- www.a.shifen.com ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3005ms rtt min/avg/max/mdev = 24.761/25.097/25.720/0.419 ms strong@foreverstrong:~$ 

2. print(os.system("ping -c 4 www.taobao.com"))

os.system(command) 同主程序是同步执行的。
