Python json到dict，基于嵌套列创建多行？

我有一个奇怪的问题，我不知道该如何处理。我基本上是在调用一个json端点，结果如下：

除了两个键有嵌套值（地址/位置）外，您可以看到它基本上是平面的。当我将其转换为数据帧时，我得到：

基本上，看起来嵌套键中的每个键都在数据帧中创建新行。这是我的密码：

import json 
import requests
import pandas as pd

companyData = requests.get(url="https://eodhistoricaldata.com/api/fundamentals/AAPL.US?api_token=OeAFFmMliFG5orCUuwAKQ8l4WWFQ67YX").json()

General =  pd.DataFrame.from_dict(companyData['General'])
General

---

在本例中，我的目标是所有内容都只是一行，任何嵌套都将在相关列中显示为json。不要为嵌套json中的每个项目创建新的重复行。

使用

max\u level

参数尝试

pd.json\u normalize（）

df = pd.json_normalize(companyData['General'],max_level=0)
print(df)

---

试试

pd.Series（companyData['General']）

回答得很好。@piRSquared对你来说意义重大，我的朋友，谢谢！谢谢，看起来棒极了。我不知道在哪里使用json_normalize vs from dict。这很有帮助。谢谢大家!@Lostsoul不客气，快乐编码！
