在 python 中导入、打印和分析 JSON 文件的问题

Question

我必须编写一个 Jupyter Notebook 来对 Profile 类别中的问答线程进行分析。要分析的数据包含在 JSON 文件中。这个文件非常大，其中包含不止一个讨论。当我导入文件并尝试在终端中可视化它时，我看到了这个错误：

JSONDecodeError: Extra data: line 855 column 1 (char 26418)

分析导入的文件，我注意到第 855 行对应于讨论的结束和下一个讨论的开始。

在我正在谈论的 json 文件的一部分之后。

In addition, some people may not think to look for settings, and so there would likely be a significant number of people reporting the lack of achievements as a bug, and / or creating discussions to ask why they don't appear to be working. At least the setting's there for those who want it.",

这是我写的代码

import json
file_json = open("/content/drive/MyDrive/Lab_SC/gh_discussions_badges.json")
data = json.load(file_json)
print (data)

这是错误

JSONDecodeError: Extra data: line 855 column 1 (char 26418)

Answer 1

您的文件不是 JSON。

您实际上是在执行以下操作：

import json

json.loads("{}{}")

这使

JSONDecodeError: Extra data: line 1 column 3 (char 2)

您需要一组对象 [{},{}] 或单个对象 {}。
