在 JSON 和 Python 中的键返回中添加键和值

Question

我有一个采用这种格式的 JSON 文件，我正在尝试插入一个键和值，作为键的值。

{
    "A": {
        "A": "2024-07-17 20:06:35.185784",
        "B": "2024-07-17 20:27:15.531860"
    },
    "B": {
        "A": "2024-07-17 20:27:15.531860",
        "B": "2024-07-17 20:27:15.531860"
        #I want to insert here "C" : "Some text"
    }
}

这是我的代码：

with open('/Users/admin/Downloads/files/date.json') as jsonfile:
    data = json.load(jsonfile)

data['B']['C'] = "Some text"        

with open('/Users/admin/Downloads/files/date.json', 'w') as jsonfile:
    json.dump(data, jsonfile, indent=4)

我收到的错误反馈：

Ignoring exception in on_voice_state_update
Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages/discord/client.py", line 378, in _run_event
    await coro(*args, **kwargs)
  File "/Users/admin/Downloads/files/sharedvc.py", line 78, in on_voice_state_update
    data[B][C] = "Some text"

KeyError: 'C'

刚刚尝试了这个脚本和文件。对我来说工作得很好。

JSON-

{
    "A": {
        "A": "2024-07-17 20:06:35.185784",
        "B": "2024-07-17 20:27:15.531860"
    },
    "B": {
        "A": "2024-07-17 20:27:15.531860",
        "B": "2024-07-17 20:27:15.531860",
        "C": "Some text"
    }
}

代码-

import json
with open('C:/Users/krupauliha/file.json') as jsonfile:
    data = json.load(jsonfile)    
data['B']['C'] = "Some text"        
with open('C:/Users/krupauliha/file.json', 'w') as jsonfile:
    json.dump(data, jsonfile, indent=4)
