无法在 Python 中使用 pandas_datareader 检索雅虎财经股票数据

Question

我运行以下代码：

import pandas_datareader.data as web
from datetime import date, datetime, timedelta
#
datetime_now = datetime.now().strftime('%Y-%m-%d %H:%M:%S')
todays_date = date.today()   # retreived in YYYY-MM-DD format
n = 7
date_n_days_ago = date.today() - timedelta(days=n)
#
mylist = ['AAPL', 'BEML.NS', 'BAJAJ-AUTO.NS', 'M&M.NS', 'JINDALSTEL.NS', 'L&TFH.NS']
#
for yahoo_symbol in mylist:
    try:
        stock_data = web.DataReader(yahoo_symbol, 'yahoo', date_n_days_ago, todays_date)
        print "success in retreiving data for: ",yahoo_symbol
    except:
        print "failed in retreiving data for: ",yahoo_symbol

这是我收到的输出：

success in retreiving data for:  AAPL
success in retreiving data for:  BEML.NS
failed in retreiving data for:  BAJAJ-AUTO.NS
failed in retreiving data for:  M&M.NS
success in retreiving data for:  JINDALSTEL.NS
failed in retreiving data for:  L&TFH.NS

我的疑问：为什么当符号为“BAJAJ-AUTO.NS”或“M&M.NS”时，我无法使用 pandas_datareader 检索雅虎股票数据，而当符号为“AAPL”或“BEML.NS”时可以这样做. 是否有任何解决方法来检索这些数据？

PS：我注意到，每当股票代码包含 "&" 或 "-" 时，我都无法使用 pandas_datareader 从雅虎财经检索该数据

谢谢。
