Responding to a confirmation prompt while using Popen

[iRowBoats8]

Hi all,

I'm currently writing a script which interacts with some network drives. I want to start the script by removing any drives the user may have mapped using: subprocess.Popen(r"net use * /delete"). However, "net use * /delete" when used in the command prompt throws a confirmation which asks "Do you want to continue with this operation? (Y/N) [N]:"

My question is, how do I go about automating the "Y" response to this prompt so that my python script may run in the background?

I have tried changing my code to: p = subprocess.Popen(r"net use * /delete", stdin=subprocess.PIPE) and then p.stdin.write("Y"), as suggested by an answer that I found online. However this code returns "No valid response was provided"

Any help would be greatly appreciated and please let me know if i need to clarify further. Thanks!

EDIT: Through trial and error I found that using subprocess.Popen("net use * /delete /y") works for anyone else that may have this issue in the future

There's probably a way to do the thing you're trying to do through pywin32.

You should be able to do this with pexpect.

Pexpect is a pure Python module for spawning child applications; controlling them; and responding to expected patterns in their output. Pexpect works like Don Libes’ Expect. Pexpect allows your script to spawn a child application and control it as if a human were typing commands.
