Python yahoo finance 数据优化

Question

我在这里找到了一个非常好的代码来检索我需要的一些数据 (Python yahoo finance error market_cap=int(data.get_quote_yahoo(str)['marketCap']) TypeError: 'int' object is not callable)：

tickers=["AAPL","GOOG","RY","HPQ"]

# Get market cap (not really necessary for you)
market_cap_data = web.get_quote_yahoo(tickers)['marketCap']

# Get the P/E ratio directly
pe_data = web.get_quote_yahoo(tickers)['trailingPE']

# print stock and p/e ratio
for stock, pe in zip(tickers, pe_data):
    print(stock, pe)

# More keys that can be used
      ['language', 'region', 'quoteType', 'triggerable', 'quoteSourceName',
       'currency', 'preMarketChange', 'preMarketChangePercent',
       'preMarketTime', 'preMarketPrice', 'regularMarketChange',
       'regularMarketChangePercent', 'regularMarketTime', 'regularMarketPrice',
       'regularMarketDayHigh', 'regularMarketDayRange', 'regularMarketDayLow',
       'regularMarketVolume', 'regularMarketPreviousClose', 'bid', 'ask',
       'bidSize', 'askSize', 'fullExchangeName', 'financialCurrency',
       'regularMarketOpen', 'averageDailyVolume3Month',
       'averageDailyVolume10Day', 'fiftyTwoWeekLowChange',
       'fiftyTwoWeekLowChangePercent', 'fiftyTwoWeekRange',
       'fiftyTwoWeekHighChange', 'fiftyTwoWeekHighChangePercent',
       'fiftyTwoWeekLow', 'fiftyTwoWeekHigh', 'dividendDate',
       'earningsTimestamp', 'earningsTimestampStart', 'earningsTimestampEnd',
       'trailingAnnualDividendRate', 'trailingPE',
       'trailingAnnualDividendYield', 'marketState', 'epsTrailingTwelveMonths',
       'epsForward', 'sharesOutstanding', 'bookValue', 'fiftyDayAverage',
       'fiftyDayAverageChange', 'fiftyDayAverageChangePercent',
       'twoHundredDayAverage', 'twoHundredDayAverageChange',
       'twoHundredDayAverageChangePercent', 'marketCap', 'forwardPE',
       'priceToBook', 'sourceInterval', 'exchangeDataDelayedBy', 'tradeable',
       'firstTradeDateMilliseconds', 'priceHint', 'exchange', 'shortName',
       'longName', 'messageBoardId', 'exchangeTimezoneName',
       'exchangeTimezoneShortName', 'gmtOffSetMilliseconds', 'market',
       'esgPopulated', 'price']

我想检索前面代码末尾的大部分注释字段，但到目前为止我已经这样做了：

import pandas_datareader as web

tickers = ["AAPL", "GOOG", "RY", "SAB.MC"]

market_cap_data = web.get_quote_yahoo(tickers)['marketCap']
pe_data = web.get_quote_yahoo(tickers)['trailingPE']
fiftytwo_low_data = web.get_quote_yahoo(tickers)['fiftyTwoWeekLowChangePercent']


for stock, mcap, pe, fiftytwo_low in zip(tickers, market_cap_data, pe_data, fiftytwo_low_data):
    print(stock, mcap, pe, fiftytwo_low)

显然我可以继续我的蛮力，但你知道有什么方法可以使代码更优雅地检索具有列名的整个字段字符串吗？

['language', 'region', 'quoteType', 'triggerable', 'quoteSourceName',
       'currency', 'preMarketChange', 'preMarketChangePercent',
       'preMarketTime', 'preMarketPrice', 'regularMarketChange',
       'regularMarketChangePercent', 'regularMarketTime', 'regularMarketPrice',
       'regularMarketDayHigh', 'regularMarketDayRange', 'regularMarketDayLow',
       'regularMarketVolume', 'regularMarketPreviousClose', 'bid', 'ask',
       'bidSize', 'askSize', 'fullExchangeName', 'financialCurrency',
       'regularMarketOpen', 'averageDailyVolume3Month',
       'averageDailyVolume10Day', 'fiftyTwoWeekLowChange',
       'fiftyTwoWeekLowChangePercent', 'fiftyTwoWeekRange',
       'fiftyTwoWeekHighChange', 'fiftyTwoWeekHighChangePercent',
       'fiftyTwoWeekLow', 'fiftyTwoWeekHigh', 'dividendDate',
       'earningsTimestamp', 'earningsTimestampStart', 'earningsTimestampEnd',
       'trailingAnnualDividendRate', 'trailingPE',
       'trailingAnnualDividendYield', 'marketState', 'epsTrailingTwelveMonths',
       'epsForward', 'sharesOutstanding', 'bookValue', 'fiftyDayAverage',
       'fiftyDayAverageChange', 'fiftyDayAverageChangePercent',
       'twoHundredDayAverage', 'twoHundredDayAverageChange',
       'twoHundredDayAverageChangePercent', 'marketCap', 'forwardPE',
       'priceToBook', 'sourceInterval', 'exchangeDataDelayedBy', 'tradeable',
       'firstTradeDateMilliseconds', 'priceHint', 'exchange', 'shortName',
       'longName', 'messageBoardId', 'exchangeTimezoneName',
       'exchangeTimezoneShortName', 'gmtOffSetMilliseconds', 'market',
       'esgPopulated', 'price']

谢谢

Answer 1

使用集合，可以得到初始集合中可以被ticker检索到的所有项，使用并集，还可以在一个列表中添加，这样就可以得到所有在集合中有值的项名您要检索的问题。

import pandas_datareader as web
import pandas as pd

tickers = ["AAPL", "GOOG", "RY", "SAB.MC"]

names = set()
for t in tickers:
    market_cap_data = web.get_quote_yahoo(t)
    names |= set(market_cap_data.columns.to_list())
names

{'ask',
 'askSize',
 'averageAnalystRating',
 'averageDailyVolume10Day',
 'averageDailyVolume3Month',
 'bid',
 'bidSize',
 'bookValue',
 'cryptoTradeable',
 'currency',
 'customPriceAlertConfidence',
 'displayName',
  ...
 'trailingAnnualDividendYield',
 'trailingPE',
 'triggerable',
 'twoHundredDayAverage',
 'twoHundredDayAverageChange',
 'twoHundredDayAverageChangePercent',
 'typeDisp'}

我知道这篇文章很老了，但我现在才看到它。查看“yfinance”库。那里有各种各样的东西！

import pandas_datareader as web
import pandas as pd
 
df = web.DataReader('AAPL', data_source='yahoo', start='2011-01-01', end='2021-01-12')
df.head()

import yfinance as yf
aapl = yf.Ticker("AAPL")
aapl
 
 
# get stock info
aapl.info
 
# get historical market data
hist = aapl.history(period="max")
 
# show actions (dividends, splits)
aapl.actions
 
# show dividends
aapl.dividends
 
# show splits
aapl.splits
 
# show financials
aapl.financials
aapl.quarterly_financials
 
# show major holders
aapl.major_holders
 
# show institutional holders
aapl.institutional_holders
 
# show balance sheet
aapl.balance_sheet
aapl.quarterly_balance_sheet
 
# show cashflow
aapl.cashflow
aapl.quarterly_cashflow
 
# show earnings
aapl.earnings
aapl.quarterly_earnings
 
# show sustainability
aapl.sustainability
 
# show analysts recommendations
aapl.recommendations
 
# show next event (earnings, etc)
aapl.calendar
 
# show ISIN code - *experimental*
# ISIN = International Securities Identification Number
aapl.isin
 
# show options expirations
aapl.options
 
# get option chain for specific expiration
opt = aapl.option_chain('YYYY-MM-DD')

结果：
