In Python 3, how can I tell if Windows is locked?

Question

How can I check whether a Windows OS workstation is locked? (e.g. Win+L or choosing the lock option after Ctrl+Alt+Del.)

I want something like ctypes.windll.us

Answer 1

You can get the window on top, when the session is locked, the function return 0.

import ctypes
user32 = ctypes.windll.User32

def isLocked():
    return user32.GetForegroundWindow() == 0
