我有一个非常简单的Pandas数据框,其中包含一个索引(类型TimedeltaIndex)和一个名为的列TotalVolume.

>> print(df)
        TotalVolume
...
09:00:00  143846.153846
09:05:00   84353.846154
09:10:00   46946.153846
09:15:00   46765.384615
09:20:00   53076.923077
09:25:00   31642.307692
09:30:00   48269.230769
...

我希望能够以09:00:00例如查询这个字典并获取143846.153846.有关信息,这是索引的结构:

>> print(df.index)
TimedeltaIndex(['07:00:00', '07:05:00', '07:10:00', '07:15:00', '07:20:00', '07:25:00', '07:30:00', '07:35:00', '07:40:00', '07:45:00', '07:50:00', '07:55:00', '08:00:00', '08:05:00', '08:10:00', '08:15:00', '08:20:00', '08:25:00', '08:30:00', '08:35:00', '08:40:00', '08:45:00', '08:50:00', '08:55:00', '09:00:00', '09:05:00', '09:10:00', '09:15:00', '09:20:00', '09:25:00', '09:30:00', '09:35:00', '09:40:00', '09:45:00', '09:50:00', '09:55:00', '10:00:00', '10:05:00', '10:10:00', '10:15:00', '10:20:00', '10:25:00', '10:30:00', '10:35:00', '10:40:00', '10:45:00', '10:50:00', '10:55:00', '11:00:00', …
