how do i catch pywintypes.api_error?

[John S. Yates, Jr.]

I can write

   try:
       ...
   except Exception, ex:
       print type(ex)
       print sys.exc_info()
       ...

and this does catch api_error:

    <type 'instance'>
    (<class pywintypes.api_error at 007C07FC>,
     <pywintypes.api_error instance at 008A7724>,
     <traceback object at 0089DB50>)

It also catches all exceptions derived from Python's
root Exception class. But when I write:

   try:
       ...
   except pywintypes.api_error, ex:
       ...

I get

    AttributeError: 'pywintypes' module has no attribute 'api_error'

Is there anyway to write an except handler that will
catch only api_error?  Alternatively, within a handler
can I determine whether or not I have an api_error?
