对不按顺序排列的字典键和值进行分组

Question

下面我有一个字典列表：

dict = [{'name': 'Sector',

  'entity': 'ORG(100.0)',

  'synonyms': "Sector:['sector', 'sphere'], , ",

  'definition': 'Sector'},

  {'name': 'Community Name',

  'entity': 'PERSON(39.74)',

  'synonyms': "Community:['biotic_community', 'community', 'community_of_interests', 'residential_area', 'residential_district']",

  'definition': 'Community'}]

如何添加将实体分组的新键，并将定义定义为值？

所需的输出（类别是新添加的键）：

dict = [{'name': 'Sector',

  'category': {

  'entity': 'ORG(100.0)',

  'definition': 'Sector'},

  'synonyms': "Sector:['sector', 'sphere'], , "},

  {'name': 'Community Name',

  'category':{

  'entity': 'PERSON(39.74)',

  'definition': 'Community'},

   'synonyms': "Community:['biotic_community', 'community', 'community_of_interests', 'residential_area', 'residential_district']"}]

我已经尝试过[{'name': i.pop('name'), 'category': i}  for I in dict]，但它只适用于按顺序排列的键，我如何修改它以便我可以选择某些键，因为entity它们definition彼此不相邻？

看来你需要data = [{'name': 'Sector',  'entity': 'ORG(100.0)',  'synonyms': "Sector:['sector', 'sphere'], , ",  'definition': 'Sector'},  {'name': 'Community Name',  'entity': 'PERSON(39.74)',  'synonyms': "Community:['biotic_community', 'community', 'community_of_interests', 'residential_area', 'residential_district']",  'definition': 'Community'}]subkeys = ['entity', 'definition']result = [{'category': {k: i.pop(k) for k in subkeys},  **i}  for i in data]print(result)输出：[{'category': {'definition': 'Sector', 'entity': 'ORG(100.0)'},  'name': 'Sector',  'synonyms': "Sector:['sector', 'sphere'], , "}, {'category': {'definition': 'Community', 'entity': 'PERSON(39.74)'},  'name': 'Community Name',  'synonyms': "Community:['biotic_community', 'community', "              "'community_of_interests', 'residential_area', "              "'residential_district']"}]

Answer 2

看起来您想转换每个对象，在这种情况下，我会选择具有自定义功能的地图。import jsondicts = [    {        'name': 'Sector',         'entity': 'ORG(100.0)',         'synonyms': "Sector:['sector', 'sphere'], , ",         'definition': 'Sector'    },    {        'name': 'Community Name',         'entity': 'PERSON(39.74)',         'synonyms': "Community:['biotic_community', 'community', 'community_of_interests', 'residential_area', 'residential_district']",         'definition': 'Community'    }]def map_func(item):    item['category'] = {'entity': item['entity'], 'definition': item['definition']}    item.pop('entity')    item.pop('definition')    return itemmapped_dicts = map(lambda x: map_func(x), dicts)print(json.dumps(list(mapped_dicts), indent=2))[  {    "name": "Sector",    "synonyms": "Sector:['sector', 'sphere'], , ",    "category": {      "entity": "ORG(100.0)",      "definition": "Sector"    }  },  {    "name": "Community Name",    "synonyms": "Community:['biotic_community', 'community', 'community_of_interests', 'residential_area', 'residential_district']",    "category": {      "entity": "PERSON(39.74)",      "definition": "Community"    }  }]
