如何使用python修改嵌套的JSON [英] How to modify nested JSON with python

问题描述

我需要使用Python更新(CRUD)嵌套的JSON文件.为了能够整体调用python函数(以更新/删除/创建)并将其写回到json文件中.

I need to update (CRUD) a nested JSON file using Python. To be able to call python function(s)(to update/delete/create) entires and write it back to the json file.

这是一个示例文件.

我正在查看 remap 库，但是不知道这是否行得通.

I am looking at the remap library but not sure if this will work.

    {
  "groups": [
    {
      "name": "group1",
      "properties": [
        {
          "name": "Test-Key-String",
          "value": {
            "type": "String",
            "encoding": "utf-8",
            "data": "value1"
          }
        },
        {
          "name": "Test-Key-Integer",
          "value": {
            "type": "Integer",
            "data": 1000
          }
        }
      ],
      "groups": [
        {
          "name": "group-child",
          "properties": [
            {
              "name": "Test-Key-String",
              "value": {
                "type": "String",
                "encoding": "utf-8",
                "data": "value1"
              }
            },
            {
              "name": "Test-Key-Integer",
              "value": {
                "type": "Integer",
                "data": 1000
              }
            }
          ]
        }
      ]
    },
    {
      "name": "group2",
      "properties": [
        {
          "name": "Test-Key2-String",
          "value": {
            "type": "String",
            "encoding": "utf-8",
            "data": "value2"
          }
        }
      ]
    }
  ]
}

推荐答案

我觉得我在您的问题中遗漏了一些东西.无论如何，据我了解，您想读取一个json文件，将数据编辑为python对象，然后将其与更新后的数据一起写回去吗?

I feel like I'm missing something in your question. In any event, what I understand is that you want to read a json file, edit the data as a python object, then write it back out with the updated data?

读取json文件:

import json

f = open("data.json")
raw_data = f.read()
f.close()

data = json.loads(raw_data)

这将创建一个字典(给定格式)，您可以根据需要操作它.假设您要写出来:

That creates a dictionary (given the format you've given) that you can manipulate however you want. Assuming you want to write it out:

json_data = json.dumps(data)

f = open("data.json","w")
f.write(json_data)
f.close()
