Thanks, but I am more after a quick way to get a list (at least find out 
about the list) of the attributes of the exception object without having 
to write a code snippet that would raise such an exception.  Ideally, I 
would like to write a function exceptionAttribute() that would return a 
list of strings corresponding to each attribute for a given exception.


def exceptionAttribute(theExceptionClass):
    """ returns the list of all attributes (as strings) for 
theExceptionClass"""
    # do whatever is required
    return theList
