How to know more about an exception?

Timmy

Hi,
I has a question about exception in python.
I know that an exception can be re-raised.
Is there any simple way provided by python itself that I can know the current exception is
just firstly occurred or it is re-raised by previous exception?
I need to know whether the exception is firstly occurred or not because I want to just display an error message if it's
firstly occur and skip display error message if it is just re-raised by previous exception.

Thanks!

No, that's not possible. What you can do is either

- wrap the exception instead of re-raising it

- set some property on the exception before re-raising.
