NIFTY BANK and NIFTY 50 quote is not printing with average value

https://kite.trade/docs/connect/v3/market-quotes/#retrieving-ltp-quotes
went through the above link and tried using quote with INFY and other stocks, it is giving all the required details as mentioned in the document.

When I try with BANK NIFTY or NIFTY 50 it is not giving out average value.
below is what i have used in the code please suggest

check3 = kite.quote('NSE:NIFTY BANK')
print(check3)

and

check3 = kite.quote('NSE:NIFTY 50')
print(check3)

and

check3 = kite.quote('NSE:INFY')
print(check3)

OUTPUT:
