按特定顺序排列字典列表 [英] Sorting list of dictionaries according to specific order

问题描述

我使用的是Python 2.6，我有两个数据存储。查询第一个按特定顺序返回文档ID列表。我使用这些ID在第二个数据存储中查找所有文档，它们返回一个字典列表（每个文档一个），但不是与原始列表相同的顺序。我现在需要重新排序这个字典列表，以便这些文件的顺序是他们的ID在第一个列表中。这样做最好的方法是什么？

解决方案

最好的（和一般的）解决方案似乎在这里给出：在python中任意排列的列表

I am using Python 2.6 and I have two data stores. Querying the first one returns a list of document IDs in a specific order. I look up all the documents at once in the second data store using these IDs, which returns a list of dictionaries (one for each doc), but not in the same order as the original list. I now need to re-sort this list of dictionaries so that the documents are in the order that their IDs were in the first list. What's the best way of doing this?

解决方案

The best (and general) solution seems to be given here: reordering list of dicts arbitrarily in python
