按特定顺序排列的词典列表

将“词典列表(每个文档一个)移到词典中,但顺序与原始列表不同”。

这个新的词典有匹配的键。

some_list= query_data_store_1()
some_other_list= query_data_store_2( some_list )

dict_of_dict = dict( (d['key'], d) for d in some_other_list )

for item in some_list:
    other_item = dict_of_dict[ item['key'] ]

    # Now you have item from the first list matching item from the second list.
    # And it's in order by the first list.

ids = ...
positions = {}
for pos, id in enumerate(ids):
   positions[id] = pos

docs = ...
docs.sort(key=lambda doc: positions[doc['id']])

最佳(一般)解决方案如下: reordering list of dicts arbitrarily in python
