将嵌套字典拆分为多个字典

Question

我想按语言将以下嵌套字典拆分为不同的字典并为每种语言创建一个新的 JSON 文件/字典。

之后我想将它们重新合并在一起。

感谢任何关于如何继续的建议！

示例：

{
  "All": {
    "label_es_ES": "Todo",
    "label_it_IT": "Tutto",
    "label_en_EN": "All", 
    "label_fr_FR": "Tout"
  },
  "Searchprofile": {
    "label_es_ES": "Perfil de búsqueda",
    "label_it_IT": "Profilo di ricerca",
    "label_en_EN": "Search profile", 
    "label_fr_FR": "Profil de recherche"
  },

到目前为止我得到了什么：

import json

store_file = open( 'test.txt' , "w" )

with open('translations.json') as json_file:
   data = json.load(json_file)
       for label, translations in data.items():
           for key in translations:
               if key==('label_en_EN'):
                   json.dump(???, store_file)
            .....'''

Answer 1

循环浏览你的字典：

from pprint import pprint

data = {
  "All": {
    "label_es_ES": "Todo",
    "label_it_IT": "Tutto",
    "label_en_EN": "All", 
    "label_fr_FR": "Tout"
  },
  "Searchprofile": {
    "label_es_ES": "Perfil de búsqueda",
    "label_it_IT": "Profilo di ricerca",
    "label_en_EN": "Search profile", 
    "label_fr_FR": "Profil de recherche"
  }
}
new_data = dict()
for word,transl_dict in data.items():
    for lbl, transl in transl_dict.items():
        if not(lbl in new_data.keys()):
            new_data[lbl] = dict()
        new_data[lbl][word] = transl

pprint(new_data)

输出：

{'label_en_EN': {'All': 'All', 'Searchprofile': 'Search profile'},
 'label_es_ES': {'All': 'Todo', 'Searchprofile': 'Perfil de búsqueda'},
 'label_fr_FR': {'All': 'Tout', 'Searchprofile': 'Profil de recherche'},
 'label_it_IT': {'All': 'Tutto', 'Searchprofile': 'Profilo di ricerca'}}

您当然可以将 label_... 字典单独转储到文件中。

编辑：如果您已经知道有哪些标签，则输出原始预期字典会更短：

labels = ["label_es_ES", "label_it_IT", "label_en_EN", "label_fr_FR"]
for label in labels:
    label_dict = {x: {label: data[x][label]} for x in data}
    pprint(label_dict)
    # or dump directly to files;
    with open(f"{label}.json", "w", encoding="utf-8") as f:
        json.dump(label_dict, f, indent=4, ensure_ascii=False)

Json 文件以 utf-8 格式编写，因此您可以在 json 中看到特殊字符。以后打开文件时别忘了指定编码（utf-8）！

from itertools import islice

def chunks(data, SIZE=10000):
    it = iter(data)
    for i in range(0, len(data), SIZE):
        yield {k:data[k] for k in islice(it, SIZE)}
        
for item in chunks({i:i for i in range(10)}, 3):
    print item
