Как на python проверить открыты ли окна?

 import psutil 
import win32gui 
import win32process 
 
 
def enum_window_callback(hwnd, pid): 
        tid, current_pid = win32process.GetWindowThreadProcessId(hwnd) 
        if pid == current_pid and win32gui.IsWindowVisible(hwnd): 
            windows.append(hwnd) 
 
for process in psutil.process_iter(): 
    pid = process.pid 
    windows = [] 
    win32gui.EnumWindows(enum_window_callback, pid) 
    windownames = [win32gui.GetWindowText(item) for item in windows] 
     
    if len(windownames): 
        exeName = process.name() 
        for windowName in windownames: 
            hwnd = win32gui.FindWindow(None, windowName) 
            print(f'"{exeName}" - "{windowName}" - "{hwnd}"')
