如何在Python中对列表排序

Question

我有Python的数据：

[
 ['prod_nominal.BloomConnectorForex.HQ', '192.168.7.14', '2670', 'branches/release'],
 ['prod_nominal.BloomConnectorFIX.HQ', '192.168.7.14', '2670', 'branches/release'],
 ['prod_nominal.IntegralConnector.HQ', '192.168.1.77', '2670', 'branches/release'], 
 ['prod_nominal.CitiConnector.HQ', '192.168.1.77', '2717', 'trunk'], 
 ['prod_nominal.SaxoConnector.HQ', '192.168.1.77', '2670', 'branches/release'], 
 ['prod_nominal.InstrumentMonitor.HQ', '192.168.1.77', '2670', 'branches/release'], 
 ['prod_nominal.PriceMonitor.HQ', '192.168.1.77', '2670', 'branches/release'], 
 ['prod_nominal.CFH_GM_Connector.HQ', '192.168.1.77', '2670', 'branches/release'], 
 ['prod_nominal.CFHConnectorMD.HQ', '192.168.1.77', '2670', 'branches/release'], 
 ['prod_nominal.FXOpenConnector.HQ', '192.168.1.77', '2670', 'branches/release'], 
 ['prod_nominal.CFHConnector.HQ', '192.168.1.77', '2670', 'branches/release'], 
 ['prod_nominal.CFH_GM_Demo_Connector.HQ', '192.168.1.77', '2670', 'branches/release'], 
 ['prod_nominal.FXCMConnector.HQ', '192.168.1.77', '2770', 'trunk'], 
 ['prod_nominal.LMAXConnector.HQ', '192.168.1.77', '2670', 'branches/release'], 
 ['prod_nominal.wide_spread_remover.HQ', '192.168.1.77', '2670', 'branches/release']
]

我想用数字（在ip地址之后）按字段对列表中的元素进行排序。Python中是否有谓词或类似的技术来实现这一点？我对Python还不熟悉。你知道吗

Answer 1

你可以这样做：

a = sorted(a, key=lambda x: int(x[2]))

或者

a.sort(key=lambda x: int(x[2]))
