【问题描述】：

我有一个 Json 文件，并且能够从中提取一些值并将它们汇总。我希望能够将结果放在正确的键上，但无法弄清楚。 以下是我的代码：

from builtins import print
import json
import jmespath
from collections import Counter

const = ['constituency A','constituency B','constituency C']
region = ['region A','region B','reigon C']
poll = ['POLLING STATION A','POLLING STATION B','POLLING STATION C','POLLING STATION   Z','POLLING STATION F']

fake = 'transaction':['region A':'constituency A':
    'POLLING STATION A':'PARTY A':10,'PARTY B':20,'PARTY C':30,'PARTY D':40,
    'POLLING STATION Z':'PARTY A':50,'PARTY B':60,'PARTY C':70,'PARTY D':80,
    'POLLING STATION B':'PARTY A':90,'PARTY B':100,'PARTY C':110,'PARTY D':120,
    'POLLING STATION F':'PARTY A':190,'PARTY B':1100,'PARTY C':1110,'PARTY D':1120,,
    ]

 a = json.dumps((fake))
 p = json.loads(a)
 j = jmespath.search('transaction[*]',p)

 ham = []
 man = set()
 for new_d in j:
     for k,v in new_d.items():
         for i_k,i_v in v.items():
             for w,c in i_v.items():
                 if w in poll and i_k in const and k in region:
                     ham.append(c)
 up = len(ham)
 i= 0
 a1=Counter()
 while i < up:
     a1 += Counter(ham[i])
     i+=1

  print(a1)

所以这就是我想要做的，结果是 a1 将被这样放置一个字典 =>[ 'region A':'constituency A':'PARTY D': 1360, 'PARTY C': 1320, 'PARTY B': 1280, 'PARTY A': 340] 当同时计算A区选区B的投票时，结果会以选区B为key添加到A区。

【参考方案1】：

我已经迭代了每个字典并计算了每个选区的党派票数。

fake = 
    'transaction': [
         'region A': 
             'constituency A': 
                
                    'POLLING STATION A': 
                        'PARTY A': 10, 'PARTY B': 20, 'PARTY C': 30, 'PARTY D': 40,
                    'POLLING STATION Z': 
                        'PARTY A': 50, 'PARTY B': 60, 'PARTY C': 70, 'PARTY D': 80,
                    'POLLING STATION B': 
                        'PARTY A': 90, 'PARTY B': 100, 'PARTY C': 110, 'PARTY D': 120,
                    'POLLING STATION F': 
                        'PARTY A': 190, 'PARTY B': 1100, 'PARTY C': 1110, 'PARTY D': 1120,
                ,
            
        
    ]


data = fake['transaction'][0]

total_result = 

for region, constituencies in data.items():
    total_result[region] = 
    for constituency, stations in constituencies.items():
        party_votes = 
        for station, parties in stations.items():
            for party, vote in parties.items():
                party_votes[party] = party_votes.get(party, 0) + vote
        total_result[region][constituency] = party_votes

print(total_result)

打印

'region A': 'constituency A': 'PARTY A': 340, 'PARTY B': 1280, 'PARTY C': 1320, 'PARTY D': 1360
