import pandas_datareader

end = "2022-12-15"
start = "2022-12-15"
stock_list = ["TATAELXSI.NS"]

data = pandas_datareader.get_data_yahoo(symbols=stock_list, start=start, end=end)

print(data)

当我运行此代码时，出现错误"TypeError: string indices must be integers"。

编辑：我已经更新了代码并将列表作为符号参数传递，但它仍然显示相同的错误

错误 ：

我有一个tickerStrings要一次性下载的股票代码 ( )列表。当我尝试使用read_csvPandas 时，它不会像我从 yfinance 下载数据时那样读取 csv 文件。

我通常通过这样的代码访问我的数据：data['AAPL']or data['AAPL'].Close，但是当我从 csv 文件中读取数据时，它不允许我这样做。

if path.exists(data_file):
    data = pd.read_csv(data_file, low_memory=False)
    data = pd.DataFrame(data)
    print(data.head())
else:
    data = yf.download(tickerStrings, group_by="Ticker", period=prd, interval=intv)
    data.to_csv(data_file)

这是打印输出：
