Python Django：处理DataFrame并执行要在chart.js中使用的计算

如何解决Python Django：处理DataFrame并执行要在chart.js中使用的计算

我正在努力弄清楚数据框。我正在尝试获取一个键值列表，其中将日期作为键，并将该日所有提供的股票的总SUM价格作为值。

我在阅读数据框时，发现有些人提到不建议使用iterrows()，因此应该在数据框内进行计算。但是我看不到应该怎么做，并且没有可以传递给chart.js数据的列表。

代码

    data = yf.download(  # or pdr.get_data_yahoo(...
        # tickers list or string as well
        tickers = "AAPL GOOGL NIO"),# use "period" instead of start/end
        # valid periods: 1d,5d,1mo,3mo,6mo,1y,2y,5y,10y,ytd,max
        # (optional,default is '1mo')
        period = "ytd",# fetch data by interval (including intraday if period < 60 days)
        # valid intervals: 1m,2m,5m,15m,30m,60m,90m,1h,1d,1wk,3mo
        # (optional,default is '1d')
        interval = "1d",# group by ticker (to access via data['SPY'])
        # (optional,default is 'column')
        group_by = 'ticker',# adjust all OHLC automatically
        # (optional,default is False)
        auto_adjust = False,# download pre/post regular market hours data
        # (optional,default is False)
        prepost = False,# use threads for mass downloading? (True/False/Integer)
        # (optional,default is True)
        threads = True,# proxy URL scheme use use when downloading?
        # (optional,default is None)
        proxy = None
    )

    logger.info(data)

    for index,row in data.iterrows():
        logger.info(row)
