You should retrieve separately result and error from get_data :
>>> eur, error = ek.get_data("EUR=FXAL", ["CF_BID", "CF_ASK", "CF_LAST", "CF_CLOSE"])
>>> eur
Instrument CF_BID CF_ASK CF_LAST CF_CLOSE
0 EUR=FXAL 1.17042 1.17056 1.17042 1.17187
Then, you can retrieve the CF_BID value :
>>> eur.iloc[0][1] (or eur["CF_BID"][0] )
1.17042
For CF_CLOSE, just modify the index :
>>> eur.iloc[0][4] (or eur["CF_CLOSE"][0] )
1.17187
edit: a like for Nick's answer that give a field name access !
