我有一个需要自动化的.sh脚本，所以它是一个我想在 python 脚本中运行的脚本：像这样：
import os

The script script.shneeds the user to input 3 fields, 1) the sudo password, 2) a string and 3) a string.
该脚本script.sh需要用户输入 3 个字段，1）sudo 密码，2）一个字符串和 3）一个字符串。
Enter password for user: xxxx #typed by me
Enter Auth Username: xxxx #typed by me

How can I make the python script to type/insert/pass those 3 needed values to script.sh.

You can use subprocess.Popento start the script and the communicatemethod to pass it input. Something like this:
您可以使用subprocess.Popen启动脚本和communicate传递输入的方法。像这样的东西：
import subprocess
p = subprocess.Popen(['./script.sh', '-p', '1234'],
stdin=subprocess.PIPE, stdout=subprocess.PIPE)
stdout, stderr = p.communicate(input='password\nauth username\nauth password\n')
