in Eikon Data APIs

I'm using the below function to grab option chain data. However, noticed that in Eikon I'm able to distinguish between Periodicity = 'Weekly' or 'Monthly', how do I achieve the same in Python API?

opt_chain = ek.get_data(chain_tic,fields)

    Assuming the question is about US equity options use field name EXPIR_CYCL in the chain request. In the example below the last column indicates which options expiration cycle the option belongs to.

    ek.get_data('0#IBM*.U',['DSPLY_NAME','EXPIR_CYCL'])
