我用雅虎财经下载了苹果的历史数据。我正在使用来自 https://pypi.org/project/yahoofinancials/
的信息from yahoofinancials import YahooFinancials
ticker = 'AAPL'
yahoo_financials = YahooFinancials(ticker)
由此我可以使用以下内容获取每周数据:
historical_price = yahoo_financials.get_historical_price_data('2020-01-05', '2021-01-05', 'weekly')
这很好用。但我正在努力将其解压缩成熊猫。很少有词典的词典和词典列表让我难倒。
当前输出为
AAPL
currency USD
eventsData {}
firstTradeDate {'formatted_date': '1980-12-12', 'date': 34547...
instrumentType EQUITY
prices [{'date': 1609736400, 'high': 133.610000610351...
timeZone {'gmtOffset': -18000}
我的问题是将上述内容解压为可用数据帧的最佳方法是什么?
答案 0 :(得分:2)
我建议使用 yfinance
代替它也是基于雅虎的:
!pip install yfinance
import yfinance
yfinance.download('AAPL', start='2019-01-01', end='2020-12-31')
输出:
Open High ... Adj Close Volume

2019-01-02 38.722500 39.712502 ... 38.562561 148158800

2020-12-30 135.580002 135.990005 ... 133.720001 96452100
这与使用完全相同:
yahoo_financials = YahooFinancials(ticker)
historical_price = yahoo_financials.get_historical_price_data('2020-01-05', '2021-01-05', 'weekly')
pd.DataFrame(historical_price['AAPL']['prices'])
