python - 使用 yahoo_fin

如何解决python - 使用 yahoo_fin

我是 Python 新手，我的目标是编写一些用于股票分析的代码。我已经安装了 yahoo_fin 并且刚刚开始尝试使用它。我已经开始使用 get_live_price

提取实时报价即

>>> get_live_price('aapl')
126.12000274658203

我正在处理以美元计价的股票以及以加元计价的股票，这使我需要以通用货币表示它们。所以我想将所有美元股票转换为加元，反之亦然。当然，在转换货币之前，我需要先确定一只股票的上市货币。我发现 yahoo_fin.stock_info 包括 get_quote_data 所以例如

>>> get_quote_data('aapl')

产生了这个字典

我对字典不熟悉，也不知道如何处理这些数据，但在那一长串数据的早期，我看到了

'货币'：'美元'

所以我的问题是，我怎样才能从这样的字典中只获取货币数据或任何其他数据。

解决方法

所以我的问题是，我如何只获取货币数据或任何其他数据与此相关的数据，来自这样的字典。

存在键值对的字典。在您的特定情况下，您可以通过以下方式访问 'currency':'USD'：

data = {'language': 'en-US','region': 'US','quoteType': 'EQUITY','quoteSourceName': 'Nasdaq Real Time Price','triggerable': True,'currency': 'USD','epsTrailingTwelveMonths': 3.687,'epsForward': 4.68,'epsCurrentYear': 4.45,'priceEpsCurrentYear': 28.476248,'sharesOutstanding': 16788100096,'bookValue': 3.936,'fiftyDayAverage': 133.55576,'fiftyDayAverageChange': -6.8364563,'fiftyDayAverageChangePercent': -0.051188033,'twoHundredDayAverage': 122.48235,'twoHundredDayAverageChange': 4.236946,'twoHundredDayAverageChangePercent': 0.034592297,'marketCap': 2127376285696,'forwardPE': 27.076775,'priceToBook': 32.194942,'sourceInterval': 15,'exchangeDataDelayedBy': 0,'tradeable': False,'marketState': 'REGULAR','regularMarketChange': -3.1506958,'regularMarketChangePercent': -2.4260383,'regularMarketTime': 1614010862,'regularMarketPrice': 126.7193,'regularMarketDayHigh': 129.72,'regularMarketDayRange': '125.6 - 129.72','regularMarketDayLow': 125.6,'regularMarketVolume': 45892833,'regularMarketPreviousClose': 129.87,'bid': 126.36,'ask': 126.3,'bidSize': 8,'askSize': 8,'fullExchangeName': 'NasdaqGS','financialCurrency': 'USD','regularMarketOpen': 128.01,'averageDailyVolume3Month': 104097755,'averageDailyVolume10Day': 84604500,'fiftyTwoWeekLowChange': 73.5668,'fiftyTwoWeekLowChangePercent': 1.3840704,'fiftyTwoWeekRange': '53.1525 - 145.09','fiftyTwoWeekHighChange': -18.370697,'fiftyTwoWeekHighChangePercent': -0.12661588,'fiftyTwoWeekLow': 53.1525,'fiftyTwoWeekHigh': 145.09,'dividendDate': 1613001600,'earningsTimestamp': 1611765000,'earningsTimestampStart': 1619607540,'earningsTimestampEnd': 1620043200,'trailingAnnualDividendRate': 0.807,'trailingPE': 34.369217,'trailingAnnualDividendYield': 0.006213906,'firstTradeDateMilliseconds': 345479400000,'priceHint': 2,'exchange': 'NMS','shortName': 'Apple Inc.','longName': 'Apple Inc.','messageBoardId': 'finmb_24937','exchangeTimezoneName': 'America/New_York','exchangeTimezoneShortName': 'EST','gmtOffSetMilliseconds': -18000000,'market': 'us_market','esgPopulated': False,'displayName': 'Apple','symbol': 'AAPL'}
print(data['currency'])

当您从字典 USD 访问键 currency 的值时，输出将为 data。
