问题描述
目前，我正在尝试根据财务数据（例如资产负债表、损益表和现金流量表）创建股票筛选器。我在互联网“yahoofinancials”上找到了一个很棒的包，它可以从雅虎获取任何股票的数据并将其输出为字典。唯一的问题是，每当我尝试访问数据时，因为它在多个字典中，我不能。我已经在互联网上搜索了几天，但唯一的资源是没有锁定在其他人内部的字典。这是我正在尝试运行的代码，然后我将显示资产负债表字典。
from yahoofinancials import YahooFinancials
ticker = input("Enter exact stock ticker in upper-case lettering: ")
yahoo_financials = YahooFinancials(ticker)
balance_sheet_data_annual = yahoo_financials.get_financial_stmts('annual','balance')
cash_flow_sheet_data_annual = yahoo_financials.get_financial_stmts('annual','cash')
income_statement_data_annual = yahoo_financials.get_financial_stmts('annual','income')
all_statement_data_annual = yahoo_financials.get_financial_stmts('annual',['income','cash','balance'])
ten_yr_bond_yield = YahooFinancials(['^TNX'])
totalStockHolderEquity = {'balanceSheetHistory'}
totalStockHolderEquityi = balance_sheet_data_annual['totalStockHolderEquity']
# tests for dictionary navigation
print(totalStockHolderEquityi)
print(balance_sheet_data_annual)
这是字典
