我有一些来自API的库存数据。问题是有时我只需要将输出的特定部分作为一个部分给出，例如：
t = ib.reqPositions()
print(t)
结果：
[Position(account='DU1314721', contract=Stock(conId=320227571, symbol='QQQ', exchange='NASDAQ', currency='USD', localSymbol='QQQ', tradingClass='NMS'), position=0.0, avgCost=0.0), Position(account='DU1314721', contract=Stock(conId=756733, symbol='SPY', exchange='ARCA', currency='USD', localSymbol='SPY', tradingClass='SPY'), position=0.0, avgCost=0.0), Position(account='DU1314721', contract=Stock(conId=73128548, symbol='DIA', exchange='ARCA', currency='USD', localSymbol='DIA', tradingClass='DIA'), position=0.0, avgCost=0.0), Position(account='DU1314721', contract=Forex('USDPLN', conId=34831481, localSymbol='USD.PLN', tradingClass='USD.PLN'), position=0.0, avgCost=0.0), Position(account='DU1314721', contract=Stock(conId=208813720, symbol='GOOG', exchange='NASDAQ', currency='USD', localSymbol='GOOG', tradingClass='NMS'), position=0.0, avgCost=0.0), Position(account='DU1314721', contract=Stock(conId=265598, symbol='AAPL', exchange='NASDAQ', currency='USD', localSymbol='AAPL', tradingClass='NMS'), position=0.0, avgCost=0.0)]
是否可以组织数据？
