how to remove peripheral device from devices and printers in python

Question

I want to remove device specific device attached to my computer when i run a script in python but am not able to do this. Have searched on the web with no solution. link 1 and link 2

I learnt i can achieve that with power shell but am not able to achieve that.

This code is able to open the cd rom successfully

import os

os.system('powershell $driveEject = New-Object -comObject Shell.Application; $driveEject.Namespace(17).ParseName("""F:""").InvokeVerb("""Eject""")')

I came across this question how to remove printer from devices and printer which there is no answer for it.

I kindly need assistance achieve such result.

Answer 1

First I prepared a powershell script (s.ps1):

$driveEject = New-Object -comObject Shell.Application
$driveEject.Namespace(17).ParseName("E:").InvokeVerb("Eject")

Then I created a Python script

import os
os.system('powershell.exe -Command  ./s.ps1  >log.txt')

After that I got an error in the log file

./s.ps1 : s.ps1 cannot be loaded because
running scripts is disabled on this system. For

After reading the article I executed the commands in cmd running under the administrator

After that, I was finally able to run the script. And I saw a pop-up in the tray with a message that I can eject the disk.
