如何使用Python的pexpect库执行root命令？

Question

I am trying to mount a drives shared folder on my system (Centos).

Since the mount command needs to be executed as a root user, I am first logging in as sudo user using the su command. After the login is successful, I want to execute my mount command.

import pexpect

cmd1 = "su"
cmd2 = "mount -t cifs -o username=abc,password=def //101.101.101.214/Volume1 /home/Juna/Drive"
pwd = "my_password"
child = pexpect.spawn(cmd1)
child.expect('Password:')
child.sendline(pwd)
child.expect('#')
child.sendline(cmd2)

I am not getting the desired results from my script. Can you please share what needs to be done or modified in my script to get the desired result.

与其交互地发送命令，不如使用-c选项给su提供要运行的命令：

child = pexpect.spawn(['su', 'root', '-c', cmd2])
