无法在Python中读取JSON对象 [英] Trouble reading JSON object in Python

问题描述

我有一个JSON对象，尝试使用Python读取，但出现了一些问题.我有一个名为"test.txt"的文件，其中包含接收到的JSON对象. "test.txt"的内容如下:

I have a JSON object that I am trying to read using Python but I am having some issues. I have a file named "test.txt" which contains the received JSON object. The contents of "test.txt" are as follows:

{ "Sections": {"Now": "Thursday 3 February 2011 08:31",  "Section": [ { "Article": [ {"audioCounter": 0, "commentsCounter": 0, "Exceprt": "Category 5 cyclone slams into flood-hit Queensland", "hasMore": "true", "ID": 44871, "important": "False", "likesCounter": 0, "photoCounter": 0, "time": "20:58", "timeStamp": "2\/2\/2011 8:59:37 PM", "timeStatus": "True", "Title": "Category 5 cyclone slams into flood-hit Queensland", "Type": "Politics", "videoCounter": 0, "viewsCounter": 2 }, {"audioCounter": 0, "commentsCounter": 0, "Exceprt": "The White House: Egypt must begin a peaceful and orderly transition of power immediately", "hasMore": "false", "ID": 44868, "important": "True", "likesCounter": 0, "photoCounter": 0, "time": "20:51", "timeStamp": "2\/2\/2011 8:52:28 PM", "timeStatus": "True", "Title": "The White House: Egypt must begin a peaceful and orderly transition of power immediately", "Type": "Politics", "videoCounter": 0, "viewsCounter": 0 }, {"audioCounter": 0, "commentsCounter": 0, "Exceprt": "Bazzi: Berri endeavors to facilitate cabinet formation", "hasMore": "true", "ID": 44866, "important": "False", "likesCounter": 0, "photoCounter": 0, "time": "20:47", "timeStamp": "2\/2\/2011 8:48:18 PM", "timeStatus": "True", "Title": "Bazzi: Berri endeavors to facilitate cabinet formation", "Type": "Politics", "videoCounter": 0, "viewsCounter": 0 }, {"audioCounter": 0, "commentsCounter": 0, "Exceprt": "Saker via Future News: Opening files era has ended, Gen.

我的python脚本:

My python script:

import json;
f = open("test.txt");
d = json.load(f);
for i in d:
    print(i);

我的输出:

Sections

这就是我所得到的.我想最后列出文章"及其属性.我曾尝试查看Python的官方文档，但发现它有点模糊.

That is all I'm getting. I would like to end up with a list of "Articles" and their properties. I've tried looking at the official Python documentation but I found it to be a little vague.

谢谢

推荐答案

在您的for i in d循环中，您正在循环字典的键.该词典仅包含一个顶级关键字"Sections"，这就是为什么您仅看到该输出的原因.

In your for i in d loop, you are looping over the keys of a dictionary. The dictionary only contains one top level key, namely 'Sections', which is why you see only that output.

我不完全了解您的JSON的结构，但是您似乎想要这样的东西:

I do not fully understand the structure of your JSON, but it appears you want something like this:

for aritcle in d['Sections']['Section'][0]['Article']:
      print article

这将打印出所有文章.
