如何使用 pandas 正确读取 json 文件

Question

目前我正在开发一个应用程序来分析堆栈溢出问题。所以我从堆栈 API 获取数据作为 json 文件，并使用以下代码读取 json 文件中的数据，如下所示。

import pandas as pd
import json
df = pd.read_json("questions_sof.json")
df.head(3)

但是输出只接收到像 json 文件这样的分离数据。但实际上我想将它们添加到表中以手动分析数据，因为它在视觉上很容易处理。

questions
1   {'tags': ['r','loops','linear-regression'], 'owner': {'re...
2   {'tags': ['vb.net', 'winforms'], 'owner': {'re...

我尝试了一些代码，但无法找到一种以适当方式可视化表格中数据的方法。您能否建议我一种在表格中显示这些数据的正确方法，或者提供一些链接以找出我自己对这个问题的答案。 json 文件包含一个从堆栈溢出中提取的问题以进行分析，我已经给出了 json 文件的示例数据。

json文件内容：

 {"questions":[
   {
     "tags": [
       "r",
       "loops",
       "linear-regression"

这是您要查找的输出吗？
