declaimed the following:
>Hi Team,

>failed !!!")
> return False
The return will never be reached -- executing "raise" will result in an
immediate transfer to ...
> except Exception as e:
... this exception handler...
> logging.error(e)
> sys.stderr.write("Dataset create failed...Exiting !!!")
> sys.exit(EXIT_STATUS_ERROR)
... which forcibly exits the program.
> return True
As a result, this True is of no real use. If the function doesn't
succeed, the program kills itself; the only way a caller gets control back
is when the function succeeds, so there is no need to test for success.
