  • and where is your code ? If page uses JavaScript then you may need Selenium or you should check what url uses JavaScript to read data and use it to get data. – furas Aug 11 '20 at 23:08
  • you could add link to this page. – furas Aug 11 '20 at 23:12
  • examples from other questions for nseindia.com but I don't know if there is example for page with chart: https://github.com/furas/python-examples/tree/master/__scraping__/nseindia.com%20-%20requests – furas Aug 11 '20 at 23:14
  • Does this answer your question?

This chart read data from urls

https://www.nseindia.com/api/chart-databyindex?index=BERGEPAINTEQN

https://www.nseindia.com/api/chart-databyindex?index=BERGEPAINTEQN&preopen=true

and you can get it with requests

This page needs header User-Agent but it can be even short 'Mozilla/5.0'.

import requests
import datetime

headers = {'User-Agent': 'Mozilla/5.0'}

url = 'https://www.nseindia.com/api/chart-databyindex?index=BERGEPAINTEQN'
#url = 'https://www.nseindia.com/api/chart-databyindex?index=BERGEPAINTEQN&preopen=true'

r = requests.get(url, headers=headers)

# --- response ---

#print(r.status_code)

data = r.json()

print('name:', data['name'])
print('identifier:', data['identifier'])
print('close price:', data['closePrice'])

prices = data['grapthData'][:10]

for item in prices:
    dt = datetime.datetime.utcfromtimestamp(item[0]/1000)
    value = item[1]
    print(dt, value)

Result

name: BERGEPAINT
identifier: BERGEPAINTEQN
close price: 551.45
