所以我正在运行我的代码，你可以在下面看到。此代码从yahoo api中提取数据并将所述数据作为CSV返回给我的计算机。但是它通过大约一半而且它停在LTM为什么会这样，我怎么能解决它......如果有人知道这个答案非常赞赏 - ＆gt;我如何每天更新这些CSV任何简单的解决方案。

错误 - ＆GT;引发RemoteDataError（＆＃39;无法读取URL：{0}＆＃39; .format（url）） pandas_datareader._utils.RemoteDataError：无法读取URL：http://ichart.finance.yahoo.com/table.csv?ignore=.csv&e=31&g=d&s=LMT&b=1&a=0&c=2000&d=11&f=2016如果您查看URL的中间，您会看到股票代码LMT。

import os
import datetime as dt
import pandas as pd
import pandas_datareader.data as web
import bs4 as bs
import pickle
import requests

def save_sp500_tickers():
    resp = requests.get('https://en.wikipedia.org/wiki/List_of_S%26P_500_companies')
    soup = bs.BeautifulSoup(resp.text, 'html.parser')
    table = soup.find('table', {'class': 'wikitable sortable'})

    tickers = []
    for row in table.findAll('tr')[1:]:
        ticker = row.findAll('td')[0].text
        tickers.append(ticker)

    with open("sp500tickers.pickle", "wb") as f:
        pickle.dump(tickers, f)

    print(tickers)
    return tickers

#save_sp500_tickers()


def get_data_from_yahoo(reload_sp500=False):
    if reload_sp500:
        tickers = save_sp500_tickers()
    else:
        with open("sp500tickers.pickle", "rb") as f:
            tickers = pickle.load(f)

    if not os.path.exists('stock_dfs'):
        os.makedirs('stock_dfs')

    start = dt.datetime(2000, 1, 1)
    end = dt.datetime(2016, 12, 31)

    for ticker in tickers:
        print(ticker)
        # just in case your connection breaks, we'd like to save our progress!
        if not os.path.exists('stock_dfs/{}.csv'.format(ticker)):
            df = web.DataReader(ticker, 'yahoo', start, end)
            df.to_csv('stock_dfs/{}.csv'.format(ticker))
        else:
            print('Already have {}'.format(ticker))

get_data_from_yahoo()

Python从yahoo api拉动sp500在股票LMT停滞
