There is another way.
#Import whole Instrument List
instrumentList = pd.DataFrame(kite.instruments())
#Hunting for the term like "20FEBFUT". This term may change in December20. So, Remember that!
mydate = datetime.datetime.now()
futappend = (mydate.strftime("%y")+mydate.strftime("%b")+"FUT").upper()
#Searching the trading symbols thats the above term
fnolist = instrumentList[(instrumentList['tradingsymbol'].str.contains(futappend))]
That’s it.
