如何从嵌套的 JSON 文件中获取数据

Question

我有一个 JSON 文件，其中包含 10 级嵌套数据。 从中获取数据的最佳方法是什么。

    [{'next': '?page=2',
     'previous': None,
    'results': [{'Accounts': [{'id': 17934,

我可以使用如下所示的静态查询一一获取数据

import json
with open("response.json", "r") as file:
  info = json.load(file) # info contains all key-value pairs
  for i in info:
      try:
          print(i["results"][0]["title"])
      except:
          print("")

输出：

IndiGo, SpiceJet combined loss could hit $1.5bn: Report
German ThyssenKrupp/ Cuts 3 thou jobs at steel business
Sameer Aggarwal Walmart India CEO

Edit1：我已经使用下面的脚本标准化了 JSON

df = pd.json_normalize(data)
print(df['results'])

输出：

0    [{'source_name': 'Factiva', 'attachments': [],...
1    [{'source_name': 'Factiva', 'attachments': [],...
2    [{'source_name': 'Factiva', 'attachments': [],...
3    [{'source_name': 'Devdiscourse', 'attachments'...
4                                                   []
5    [{'source_name': 'Factiva', 'attachments': [],...
6    [{'source_name': 'Factiva', 'attachments': [],...
7    [{'source_name': 'The Globe and Mail', 'attach...

我如何使用循环获取所有数据？ 请帮助我是 Python 新手
