Launch an urgent window using Python and Xlib with the UrgencyHint flag

I am trying to fix a bug in lxpanel's taskbar plugin, and needed to launch an urgent window. Here's how I did it in a little python.

#!/usr/bin/python

# urgent.py -- launch an urgent window (Copyright messages are at the bottom)

# To use:
# sudo apt-get install python-xlib
# ./urgent.py

import sys
import Xlib
from Xlib import X, display, Xutil

d = display.Display()
s = d.screen()
w = s.root.create_window(
   50, 50, 300, 200, 2,
   s.root_depth,
   X.InputOutput,
   X.CopyFromParent,
   background_pixel = s.white_pixel,
)

w.set_wm_name( 'Urgent!' )
w.set_wm_hints( flags = Xutil.UrgencyHint )

w.map()

try:
   while 1:
       e = d.next_event()
except Xlib.error.ConnectionClosedError:
   pass
