数据通过 JavaScript 动态加载。您可以使用requests模块来模拟它。

例如：

import json
import requests


url="https://www.nseindia.com/get-quotes/equity?symbol=ITC"
api_url = 'https://www.nseindia.com/api/quote-equity?symbol={symbol}&section=trade_info'
headers = {'User-Agent': 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:77.0) Gecko/20100101 Firefox/77.0',}

symbol = url.split('=')[-1]
data = requests.get(api_url.format(symbol=symbol), headers=headers).json()

# uncomment this to print all data:
# print(json.dumps(data, indent=4))

print('Total market capitalization:', data['marketDeptOrderBook']['tradeInfo']['totalMarketCap'])

印刷：

Total market capitalization: 24082488.32

尝试使用 Xpath 进行查找。我无法访问服务器，否则我想检查自己。
