通过在 python 中使用新键对字典进行分区来创建字典

Question

我有这样的字典：

{"Topic":"text","title":"texttitle","abstract":"textabs","year":"textyear","authors":"authors"}

我想创建另一个列表如下：

[{"label":{"Topic":"text","title":"texttitle","abstract":"textabs","year":"textyear","authors":"authors"},"value":
{"Topic":"text","title":"texttitle","abstract":"textabs","year":"textyear","authors":"authors"}}]

我已经用 .items() 尝试了一些方法，但其中 none 给出了想要的结果。

Answer 1

这是你想要的吗？

dict_ = {"Topic":"text","title":"texttitle","abstract":"textabs","year":"textyear","authors":"authors"}
output = [{"label": dict_ , "value": dict_ }]
print(output)

[{"label":{"Topic":"text","title":"texttitle","abstract":"textabs","year":"textyear","authors":"authors"},"value":
{"Topic":"text","title":"texttitle","abstract":"textabs","year":"textyear","authors":"authors"}}] == [{"label": dict_ , "value": dict_ }]

给予True

Answer 2

根据我的评论，下面是我将假设键和输出的代码：

    # Could be the keys would get from somewhere
    vals = ["1","2","3","4"]
    # Probably same coming from external sources
    example_op = 
    {"Topic":"text","title":"texttitle","abstract":"textabs","year":"textyear","authors":"authors"}
    #Global list
    item_list = []
    temp_dict = {}
    for key in vals:
        temp_dict[key] = example_op
    item_list.append(temp_dict)

列表的最终输出为：

Out[9]: 
[{'1': {'Topic': 'text',
   'title': 'texttitle',
   'abstract': 'textabs',
   'year': 'textyear',
   'authors': 'authors'},
  '2': {'Topic': 'text',
   'title': 'texttitle',
   'abstract': 'textabs',
   'year': 'textyear',
   'authors': 'authors'},
  '3': {'Topic': 'text',
   'title': 'texttitle',
   'abstract': 'textabs',
   'year': 'textyear',
   'authors': 'authors'},
  '4': {'Topic': 'text',
   'title': 'texttitle',
   'abstract': 'textabs',
   'year': 'textyear',
   'authors': 'authors'}}]
