Subprocess command prompt (Windows)

[arnaur]

I changed it a bit adding flush() but I still can't figure it to work.
This is the code:

from subprocess import *

p = Popen(['cmd', '/k', 'Command that does something and asks for a password'], stdin=PIPE)
p.stdin.write(b'test\r\n' *2)
p.stdin.flush()

I also removed the shell=True because it's not recommended in the python subprocess docs. If you remove it you need to add 'cmd', '/k' to make it work. The /k will open the terminal and run the command or you can run /c to just run it without opening a terminal.

It still asks me for password and to verify it so it's not working yet.
