我试图通过以下代码从雅虎获取股票信息。
import pandas_datareader.data as web
import datetime
start = datetime.datetime(2010, 1, 1)
end = datetime.datetime(2015, 12, 31)
f = web.DataReader('SNE', 'yahoo', start, end)
print(f)
但是有如下错误.... 请有人帮帮我..

如果您想使用雅虎财务，请使用Yahoo_finance API。
from yahoo_finance import Share
当您想要检索特定共享使用的值时：
Share('<Your Share Ticker Name>')
然后您可以检索历史数据以及
之类的内容Share('Your Share Ticker Name>').get_historical(<start_date>, <end_date>)
希望这有帮助
