在字典中为一个键添加多个值的列表或字典

Question

第一次在这里发帖，如果不合适，请道歉。 我有两个字典，键和列表作为值。我需要给字典中的列表元素分配一个列表，它与另一个字典2中的列表元素相匹配。你知道吗

Dictionary 1
{'S': ['Close Coupled', 'Wall Hung', 'Btw'], 'E':['Bifold', 'Hinge', 'Sliding', 'Pivot']}

Dictionary 2
{'Close Coupled': ['Close Coupled Contract', 'Close Coupled Open Back', 'Close Coupled Open Back Rimless'], 'Wall Hung': ['Wall Hung Contract', 'Wall Hung Rimless'],'Btw': ['BTW Contract', 'BTW Rimless'], 'Bifold': ['700', '800', '900', '1000'], 'Hinge': ['700', '800', '900', '1000'], 'Sliding': ['700', '800', '900', '1000'], 'Pivot': ['700', '800', '900', '1000']} 

Result I am trying to get is.
{'S': {'Close Coupled':['Close Coupled Contract', 'Close Coupled Open Back', 'Close Coupled Open Back Rimless'], 'Wall Hung': ['Wall Hung Contract', 'Wall Hung Rimless'], 'Btw': ['BTW Contract', 'BTW Rimless'], 'E': 'Bifold':['700', '800', '900', '1000'], 'Hinge':['700', '800', '900', '1000'],'Sliding':['700', '800', '900', '1000'], 'Pivot':['700', '800', '900', '1000']}

在他的字典之后，我有另一本字典，它将以同样的方式添加。它就像一个树结构或嵌套的，但我无法建立我的逻辑分配字典到每个匹配的第一字典列表元素。你知道吗

如果不清楚，请告诉我，我会尽量解释清楚的。你知道吗

谢谢

Answer 1

一种方法是循环遍历第一个字典，并从第二个字典中获取与同名键对应的列表。例如：

d1 = {'S': ['Close Coupled', 'Wall Hung', 'Btw'], 'E':['Bifold', 'Hinge', 'Sliding', 'Pivot']}
d2 = {'Close Coupled': ['Close Coupled Contract', 'Close Coupled Open Back', 'Close Coupled Open Back Rimless'], 'Wall Hung': ['Wall Hung Contract', 'Wall Hung Rimless'],'Btw': ['BTW Contract', 'BTW Rimless'], 'Bifold': ['700', '800', '900', '1000'], 'Hinge': ['700', '800', '900', '1000'], 'Sliding': ['700', '800', '900', '1000'], 'Pivot': ['700', '800', '900', '1000']}
result = dict()

for key, values in d1.items():
    result[key] = dict()
    for value in values:
        result[key][value] = d2[value]

print(result)

# OUTPUT (print does not output indented results shown here for readability only)
# {
#      'S': {
#          'Close Coupled': ['Close Coupled Contract', 'Close Coupled Open Back', 'Close Coupled Open Back Rimless'],
#          'Btw': ['BTW Contract', 'BTW Rimless'],
#          'Wall Hung': ['Wall Hung Contract', 'Wall Hung Rimless']
#          },
#      'E': {
#          'Bifold': ['700', '800', '900', '1000'],
#          'Hinge': ['700', '800', '900', '1000'],
#          'Sliding': ['700', '800', '900', '1000'],
#          'Pivot': ['700', '800', '900', '1000']
#          }
# }

您可以使用dict理解来执行以下操作：

{keys : {m : d2.get(m) for m in values} for keys, values in d1.items()}


{'S': {'Close Coupled': ['Close Coupled Contract',
   'Close Coupled Open Back',
   'Close Coupled Open Back Rimless'],
  'Wall Hung': ['Wall Hung Contract', 'Wall Hung Rimless'],
  'Btw': ['BTW Contract', 'BTW Rimless']},
 'E': {'Bifold': ['700', '800', '900', '1000'],
  'Hinge': ['700', '800', '900', '1000'],
  'Sliding': ['700', '800', '900', '1000'],
  'Pivot': ['700', '800', '900', '1000']}}

数据：

d1 = {'S': ['Close Coupled', 'Wall Hung', 'Btw'], 'E':['Bifold', 'Hinge', 'Sliding', 'Pivot']}
d2 = {'Close Coupled': ['Close Coupled Contract', 'Close Coupled Open Back', 'Close Coupled Open Back Rimless'], 'Wall Hung': ['Wall Hung Contract', 'Wall Hung Rimless'],'Btw': ['BTW Contract', 'BTW Rimless'], 'Bifold': ['700', '800', '900', '1000'], 'Hinge': ['700', '800', '900', '1000'], 'Sliding': ['700', '800', '900', '1000'], 'Pivot': ['700', '800', '900', '1000']}

Answer 3

我想我没有正确理解你的问题。不过，请检查这个代码，如果它不适合你的需要，请让我知道。你知道吗

d1= {'S': ['Close Coupled', 'Wall Hung', 'Btw'], 'E':['Bifold', 'Hinge', 'Sliding', 'Pivot']}

d2= {'Close Coupled': ['Close Coupled Contract', 'Close Coupled Open Back', 'Close Coupled Open Back Rimless'], 'Wall Hung': ['Wall Hung Contract', 'Wall Hung Rimless'],'Btw': ['BTW Contract', 'BTW Rimless'], 'Bifold': ['700', '800', '900', '1000'], 'Hinge': ['700', '800', '900', '1000'], 'Sliding': ['700', '800', '900', '1000'], 'Pivot': ['700', '800', '900', '1000']}

final_dict= {} # create a dictionary to store the final answer
for item in d1:
    temp= dict() # temporary dictionary
    for i in item d1[item]:
        temp[i]= d2[i]
    final_dict[item]= temp

输出
打印（最终记录）

{'E': {'Bifold': ['700', '800', '900', '1000'],
  'Hinge': ['700', '800', '900', '1000'],
  'Pivot': ['700', '800', '900', '1000'],
  'Sliding': ['700', '800', '900', '1000']},
 'S': {'Btw': ['BTW Contract', 'BTW Rimless'],
  'Close Coupled': ['Close Coupled Contract',
   'Close Coupled Open Back',
   'Close Coupled Open Back Rimless'],
  'Wall Hung': ['Wall Hung Contract', 'Wall Hung Rimless']}} `
