I wrote the below code

    @wraps(func)
    def decorated_function(*args, **kwargs):
        try:
            return func(*args, **kwargs)
        except Exception:
            e = sys.exc_info()[1]
            if isinstance(e, LibcloudError):
                raise e
            if (len(args) >= 1):
                driver = args[0]
            else:
                driver = None
            fault = getattr(e, 'fault', None)
            if (fault and getattr(fault, 'string', None)):
                message = fault.string
            else:
                message = str(e)
            raise LibcloudError(value=message, driver=driver)
    return decorated_function

What's a good function header?
