用重复的键更新字典，并保持每个键的索引在Python中相同

Question

我正试图用字典类型信息更新json有效载荷，并保持关键位置与以前相同，因为它是我正在工作的任务所要求的。

注意我理解typedict的实现不允许重复密钥，但我确实需要这样做，所以任何变通或黑客的方法都会有所帮助。

我有一个从json文件加载的有效载荷

payload.json

{
"name": "",
"address": "",
"age": " ",
"ethnicities": "",
"select": "",
"sub-ethnicities": "",
"select": "",
"option1": "",
"option2": ""
}

加载

payload = json.load(open("payload.json"))

I have The info:

info = {
"name": "Spock",
"ethnicities": "Vulcan",
"select": "paternal",
"sub-ethnicities": "human",
"select": "maternal",
}

我正试图将上述信息插入有效载荷，并保持关键索引的方式。

预期结果为

{
"name": "Spock",
"address": "",
"age": "",
"ethnicities": "Vulcan",
"select": "paternal",
"sub-ethnicities": "human",
"select": "maternal",
"option1": "",
"option2": ""
}

谢谢你的好意。

Usingdata | info或data.update(信息)将删除重复的密钥，这违背了我试图存档的目标。

例如期望的结果是:

{
"name": "Spock",
"address": "",
"age": "",
"ethnicities": "Vulcan",
"select": "paternal",
"sub-ethnicities": "human",
"select": "maternal",
"Extra-ethnicities": "Asian",
"select": "Asian"
}

但是我得到的是重复的密钥被删除了。

"name": "Spock",
"address": "",
"age": "",
"ethnicities": "Vulcan",
"select": "paternal",
"sub-ethnicities": "human",
"Extra-ethnicities": "Asian",
}

在Python 3.9中作为Union操作符添加了用于此操作的操作符:

payload_with_info = payload | info
print(payload_with_info)
>>>
{
'address': '',
'age': ' ',
'ethnicities': 'Vulcan',
'name': 'Spock',
'option1': '',
'option2': '',
'select': 'maternal',
'sub-ethnicities': 'human'
}
