将字典中具有多个值的字典字典键映射到python中的json

问题描述：

我正在尝试将具有多个值的一个键的字典映射到python中.这就是我得到的.

I am trying to map a dictionary with one key that has multiple values into python. Here is what I got.

import json

list =['abe','matt','roscoe']
key="name"
nodes={}
nodes.setdefault(key,list)
['abe', 'matt', 'roscoe']

json_nodes =json.dumps(nodes)
json_nodes
'{"name": ["abe", "matt", "roscoe"]}'

但是我想要一个与此类似的json文件 [ { "name":"abe" }， { "name":"matt" }， { 名称":"roscoe" } ]

But I would like to have a json file similar to this [ { "name": "abe" }, { "name": "matt" }, { "name": "roscoe" } ]

任何建议将不胜感激.提前致谢.

Any suggestions will be greatly appreciated. Thanks in advance.

答

您有一个这样的名称列表

You have a list of names, like this

>>> names = ['abe', 'matt', 'roscoe']

您只需要迭代名称，并在每次迭代中创建一个新字典以获取字典列表，像这样

You just need to iterate the names, and create a new dictionary on every iteration to get the list of dictionaries, like this

>>> json.dumps([{"name": name} for name in names])
[{"name": "abe"}, {"name": "matt"}, {"name": "roscoe"}]

在这里

[{"name": name} for name in names]

称为 List Comprehension .这是生成新列表的便捷技术.在我们的例子中，我们用for name in names遍历names.在每次迭代中，name将具有与该迭代相对应的当前名称，并且我们使用{"name": name}创建一个新字典.

is called List Comprehension. It is a convenient technique to generate new lists. In our case, we iterate over names with for name in names. On every iteration, name will have the current name corresponding to the iteration and we create a new dictionary with {"name": name}.
