Python input old ISIN and return RIC

In excel I can use RSearch to do this....

=RSearch("EQUITY","Search; SE0000143521","NBROWS:1",,)

and it will return the RIC even though the ISIN has been updated. Can I do this in python using symbology somehow? I see I can return the PermanentID for the security, but that is about all. RIC and other codes are NaNs?

With Eikon Data API, if you set bestMatch to False, it will return a list of mapped RICs.

Hi when I input bestMatch to the python code it returns an error, "unexpected keyword argument 'bestMatch' " Is there something else I need to change

I think you must have an older version of eikon package installed. Upgrade eikon library from PyPI: run "pip install --upgrade eikon".
