找到共同的關鍵：在字典值對非可哈希鍵和值

我有如下的詞典列表：找到共同的關鍵：在字典值對非可哈希鍵和值

有列表中的約2000字典。現在我想在列表中的所有字典中找到公用密鑰：值對。出於同樣的，我用下面的函數：

def twodict_intersec(json1, json2): 
    d = {x:json1[x] for x in json1 if x in json2} 
    return d 

for i in range(0,10,1): 
    print(i) 
    if i == 0: 
     res = twodict_intersec(json_list[i], json_list[i+1]) 
    else: 
     res = dict_intersect(res, json_list[i+1]) 
print(res)

但輸出是一樣的東西下面，每個鍵包含所有值的列表，而不是共同的價值

res = {'EchoTime': [[[[[[[[[0, 0], 0], 0], 0], 0], 0], 0], 0], 0], 'FlipAngle': [[[[[[[[[90, 90], 90], 90], 90], 90], 90], 90], 90], 90], 'ManufacturerModelName': [[[[[[[[['TrioTim', 'TrioTim'], 'TrioTim'], 'TrioTim'], 'TrioTim'], 'TrioTim'], 'TrioTim'], 'TrioTim'], 'TrioTim']}

我不能夠得到輸出，其中每個關鍵字只有一個在所有詞典中通用的值，而不是上面的情況。有人能指出我的錯誤嗎？

您可以比較所有在你的字典列表這樣的元素：

import copy 
li = [{ 
     "keep this value":5, 
     "remove this":59 
    },{ 
     "keep this value":5, 
     "remove this":12 
    }] 

def compareList(li): 
    result = copy.deepcopy(li[0]) 
    for element in li: 
     for key in element: 
      if key in result and result[key] != element[key]: 
       del result[key] 
    return result 

print (compareList(li))

你的意思是我需要用這個'result'我從上面的功能得到我？ – learnningprogramming
