如何建立孩子的父母关系

Question

所以我完全被困住了。我有一些字典需要按“ StartingSequenceNumber”进行排序。在执行此操作之前，尽管我需要修改列表，以便将父级的子级嵌套在其父级下方。

这是对象：

我真正想要的条目是：

{'ParentShardId': 'shardId-00000001560330042571-05db45b1',
 'SequenceNumberRange': {'StartingSequenceNumber': '2637969900000000035651597823'},
 'ShardId': 'shardId-00000001560343013811-47406cbf'}

上面的条目是以下条目的最新子级：

{'SequenceNumberRange': {'EndingSequenceNumber': '2633238500000000007213849718',
                          'StartingSequenceNumber': '2633238500000000007213849718'},
  'ShardId': 'shardId-00000001560257151491-87e08366'}

该条目丢失了孩子。

所以我需要将所有孩子嵌套在父母的下面，然后对列表和孩子列表进行排序。

这有意义吗？ ...我未包含任何代码，因为我不知道该如何处理。任何帮助表示赞赏！
