import requests
from bs4 import BeautifulSoup
headers = {'User-Agent': 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:80.0) Gecko/20100101 Firefox/80.0'}
url = 'https://www.nseindia.com/api/option-chain-indices?symbol=BANKNIFTY'
with requests.session() as s:
# load cookies:
s.get('https://www.nseindia.com/get-quotes/derivatives?symbol=BANKNIFTY', headers=headers)
# get data:
data = s.get(url, headers=headers).json()
# print data to screen:
print(json.dumps(data, indent=4))
