Appended is a script that is a fairly straight-forward conversion of the
code in the above article to Python. Needs ctypes and comtypes.
Python 2.5 already includes ctypes; comtypes can be installed
with 'easy_install comtypes'.

from ctypes import windll, oledll, WinError, byref, POINTER
from ctypes.wintypes import POINT

# create wrapper for the oleacc.dll type library
GetModule("oleacc.dll")
# import the interface we need from the wrapper
from comtypes.gen.Accessibility import IAccessible

"Return the cursor coordinates"
pt = POINT()
if not windll.user32.GetCursorPos(byref(pt)):
