Python: converting a list of dictionaries to json
提问by Apoorv Ashutosh
I have a list of dictionaries, looking some thing like this:
我有一个字典列表，看起来像这样：
list = [{'id': 123, 'data': 'qwerty', 'indices': [1,10]}, {'id': 345, 'data': 'mnbvc', 'indices': [2,11]}]
and so on. There may be more documents in the list. I need to convert these to one JSON document, that can be returned via bottle, and I cannot understand how to do this. Please help. I saw similar questions on this website, but I couldn't understand the solutions there.
等等。列表中可能还有更多文档。我需要将这些转换为一个 JSON 文档，该文档可以通过 Bottle 返回，但我无法理解如何执行此操作。请帮忙。我在这个网站上看到了类似的问题，但我无法理解那里的解决方案。

use json library
使用 json 库
import json
json.dumps(list)
by the way, you might consider changing variable list to another name, listis the builtin function for a list creation, you may get some unexpected behaviours or some buggy code if you don't change the variable name.
顺便说一句，您可能会考虑将变量列表更改为另一个名称，它list是用于创建列表的内置函数，如果您不更改变量名称，您可能会遇到一些意外行为或一些错误代码。

To convert it to a single dictionary with some decided keys value, you can use the code below.
要将其转换为具有某些确定键值的单个字典，您可以使用下面的代码。
data = ListOfDict.copy()
PrecedingText = "Obs_"
ListOfDictAsDict = {}
for i in range(len(data)):
ListOfDictAsDict[PrecedingText + str(i)] = data[i]

import json
list = [{'id': 123, 'data': 'qwerty', 'indices': [1,10]}, {'id': 345, 'data': 'mnbvc', 'indices': [2,11]}]
Write to json File:
写入 json 文件：
with open('/home/ubuntu/test.json', 'w') as fout:
json.dump(list , fout)
Read Json file:
读取 Json 文件：
with open(r"/home/ubuntu/test.json", "r") as read_file:
data = json.load(read_file)
print(data)
#list = [{'id': 123, 'data': 'qwerty', 'indices': [1,10]}, {'id': 345, 'data': 'mnbvc', 'indices': [2,11]}]

response_json = ("{ \"response_json\":" + str(list_of_dict)+ "}").replace("\'","\"")
response_json = json.dumps(response_json)
response_json = json.loads(response_json)
