set_window_attribute = ct.windll.dwmapi.DwmSetWindowAttribute
get_parent = ct.windll.user32.GetParent
hwnd = get_parent(window.winfo_id())
rendering_policy = DWMWA_USE_IMMERSIVE_DARK_MODE
value = 2
value = ct.c_int(value)
set_window_attribute(hwnd, rendering_policy, ct.byref(value), ct.sizeof(value))Here is the Example :
