在python中解析Json文件以返回特定值

我对编码还不熟悉，在将JSON文件中的值分配给python变量时遇到了麻烦，不管我怎么做，我仍然会得到相同的“keyrerror”。我的最终目标是从API调用返回一个特定的值。例如，如何从Python中的以下JSON转换API调用返回'list_price'变量？多谢各位

print(response.json())

---

似乎它必须是基于JSON的“列表价格”而不是“列表价格”

您可以按如下方式访问节点，更改API响应的test.json：

导入json
打开（“test.json”）作为json_文件：
data=json.load（json_文件）
对于数据[“数据”][“结果”]中的p：
打印（p[“价目表”]）

结果:

python readJson.py
30000
60000

此处没有“标价”元素。有两个“标价”元素，分别位于

json[“数据”][“结果”][0][“标价”]

和

json[“数据”][“结果”][1][“标价”]
