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

Based on @Stardidi answer, this worked for me (Windows 10 Pro):

import time
import win32gui
import win32api
import win32con
import win32process

while True:
    time.sleep(1)
    _, pid = win32process.GetWindowThreadProcessId(win32gui.GetForegroundWindow())

    try:
        handle = win32api.OpenProcess(win32con.PROCESS_ALL_ACCESS, False, pid)
        filename = win32process.GetModuleFileNameEx(handle, 0)
    except Exception as _e:
        filename = "LockApp.exe"
        del _e

    current_status = "locked" if "LockApp" in filename else "unlocked"
