from bs4 import BeautifulSoup
import pandas as pd

soup = BeautifulSoup(r.content, "html.parser")

Answer 1

您可以使用#stock_code > option代替stock_id来获取股票下拉列表中的数据。您可以尝试一下：

url ="http://www.moneycontrol.com/india/fnoquote/reliance-industries/RI/2020-07-30"
headers = {'User-Agent': 'Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)'}

from bs4 import BeautifulSoup
import requests
r = requests.get(url, headers = headers)
soup = BeautifulSoup(r.content, "html.parser")
a  = soup.select("#stock_code > option")

for i in a:
      print(i.text)

输出将是：
