Options Data extraction for python trading.

Hi Everyone.

Kindly assist me with the queries, as I am new to this forum. In case there are more relevant forums, do suggest me as well.

Can you assist me with the below issue:

01.
option_chain_data = yfinance.Ticker('AARTIIND.NS').option_chain('2021-07-29')

I am getting the exception message:
list index out of range

02.

I am trying to fetch the StochasticRSI for AARTIIND.NS with the value displayed in Zerodha UI as 7.20 as in below screenshot



I am looking forward to ta-lib python library but none of the stochastics functions provide even approximate to this value.

Any other python library where I can fetch the value of 7.20 would work equally well.

Thanks.
