How can I using yfinance to get fundamental ratios ( such as P/E, P/B )
我一直想知道如何获得一系列基本面数据，例如使用 yfinance 的公司的 P/E 比率。多家公司的历史比率。
我试过了
import yfinance as yf
rio=yf.Ticker("RIO.AX")
rio.financials
但我的结果是空数据框
任何人都可以帮忙吗？或我可以阅读的任何文档
非常感谢
您以后可能想 google 尝试查找 python 软件包的文档。这是此软件包文档的 link。
yfinance 似乎无法再检索公司财务信息（自 2020 年 10 月以来我就没用过）
但是，如果您不反对尝试另一个库，可以使用 yahoo_fin
pip install yahoo_fin
pip install requests_html
安装后：
import yahoo_fin.stock_info as si
msft_data = si.get_quote_table("MSFT")
字典如下所示：

在#get fundamentals（第 375 行左右）中插入注释：
#data = utils.get_json(url+'/financials', proxy)
并写下这两行：
url = "{}/{}/financials".format(self._scrape_url, self.ticker)

使用以下代码行会更容易一些。更简单，输出产生一个 pandas df，尾随和前向 P/E 比率作为 150 个值之一：

df = pd.DataFrame.from_dict(dict,orient='index')
