Ticker 对象没有属性“stats” 与 yfinance 相关的问题

问：

这是我得到的错误。 “ AttributeError： 'Ticker' 对象没有属性 'stats' ”

我假设它没有创建 asset.stats（） 供它访问或存储 ['价格']['常规市场价格']

还是与yFinance的tickers.tickers问题有关，无法评估？访问多个代码的 yfinance Ticker 对象会导致 AttributeError

有人可以帮忙回答这个问题或引导我朝着正确的方向前进吗？ 谢谢你:)（我的第一篇文章在这里）

我尝试更改资产 = yf。股票代码（ticker）到yf。股票代码（tickers） YF。股票代码（股票代码）

在代码块的第二个块上 options_obj = option_chains（underlying_symbol） underlying_symbol最初是“aapl”，我将其更改为代码“DVN”。

所有其他图表显示/绘制 DVN 信息。

我以为它会存储期权信息。
