.json中的Python编辑/重命名键名 [英] Python Edit/Rename Key Names in .json

问题描述

是否可以更改密钥名称? 我需要像示例中一样更改名称"Class123".我可以更改值，但不知道如何更改键名.

Is there a way to change the Key name? I need to change the name "Class123" like it is in the Example. I can change the Value but I don't know how to change the key name.

示例.json:

{
    "Class123": "classvalue", 
    "name1": {
        "name2": {
            "name3": {
                "Y": 158.8, 
                "X": 201.46
            }, 
            "name4": {
                "Y": 159.68, 
                "X": 200.32
            }
        }
    }
}

从这样开始:

with open('my.json') as json1:
    data = json.load(json1)
    for item in data:

推荐答案

无法更改"键名. 最好的办法是使用pop将值复制到另一个键:

There is no way to "change" a key name. The best you can do is to copy the value to another key by using pop:

d = {'old_name': 1}
d['new_name'] = d.pop('old_name')
print(d)
# {'new_name': 1}
