Suppress error text while requesting data in Eikon API

haykaz.aramyan

I am testing the validity of a RIC trying both "try.. Except" (as suggested also here) and "With Suppress" functions to continue the loop and get correct RICs into a list. Although, the code works and adds correct RICs to the list I still see the message telling the RIC is incorrect. Please see attached the screenshot and putting one of them here below as well: try_except.png

RICs = ['NDXl1721A8290.U^L21', 'NDXl1721A8275.U^L21', 'NDXd1621A6275.U^D21','NDXd1621A6300.U^D21']

valid_rics = []

for RIC in RICs:

with suppress(ek.EikonError):

a = ek.get_timeseries(RIC, fields = ['CLOSE'], start_date = '2021-01-01', end_date ='2021-04-18',interval='daily' )

valid_rics.append(RIC)

valid_rics

Is there a way to hide that? Please also note that error text appeared while using the loop and it is ignored when the code is run without a loop for a single RIC.

I would appreciate if you help to find a way of suppressing error message while using the loop.

Hi @haykaz.aramyan,

Messages arn't displayed because of an EikonError exception, it's logged as warnings.
That's why "with suppress(ek.EikonError)" has no effect.

There is mainly 3 options to stop warning at screen:

1. Disable all warnings (from any lib):

   import warnings
   warnings.filterwarnings("ignore")

2. Disable displayed warnings from eikon:

   import logging
   import eikon as ek
   ...
   ek.set_app_key("xxxxxxxxxx")
   logger = logging.getLogger("pyeikon")
   logger.propagate = False
   ...

3. Reduce log level to ERROR (warnings will be ignored):

   import logging
   import eikon as ek
   ...
   ek.set_app_key("xxxxxxxxxx")
   ek.set_log_level(logging.ERROR)
   ...

Hi
@pierre.faurel, Is it possible to set these warning logs to go into a single file?

Thanks,
