下载历史股指数据

Question

我有以下谷歌金融股票指数（NSE：NIFTY50）的数据here。我想下载上面的数据为csv，以便我可以对它做一些分析。我如何下载它？如果可以的话，我宁愿使用python。

Answer 1

您应该能够使用下面的代码下载股票数据。

import requests 
from bs4 import BeautifulSoup 
import pandas as pd 

url = "https://www.google.com/finance/historical?cid=207437&startdate=Jan%201%2C%201971&enddate=Jul%201%2C%202017&start={0}&num=30" 
#change this to 138 
how_many_pages=3 
start=0 

for i in range(how_many_pages): 
    new_url = url.format(start) 
    page = requests.get(new_url) 
    soup = BeautifulSoup(page.content, "html5lib") 
    table = soup.find_all('table', class_='gf-table historical_price')[0] 

    columns_header = [th.getText() for th in table.findAll('tr')[0].findAll('th')] 
    data_rows=table.findAll('tr')[1:] 
    data=[[td.getText() for td in data_rows[i].findAll(['td'])] for i in range(len(data_rows))] 

    if (start == 0): 
     final_df = pd.DataFrame(data, columns=columns_header) 
    else: 
     df=pd.DataFrame(data, columns=columns_header) 
     final_df = pd.concat([final_df, df],axis=0) 
    start += 30 
#write your code to save final_df to csv
