试图将嵌套的 JSON 转换为当前数据框的列。我该如何做到这一点？注意：字典的 JSON 函数列表重复 600 多次

{
"Functions": [
    {
        "CodeSha256": "",
        "CodeSize": 
        "Description": "",
        "Environment": {
            "Variables": {

                "COMMIT_HASH": ",
                "CodeSha256": "",
                "ECS_LOG_STREAM": "",
                "ELASTIC_SEARCH_DOMAIN_ENDPOINT": "",
                "ENVIRONMENT": "prod",
                "SERVICE_NAME": "testingservicename",
                "SERVICE_OWNER": "testingserviceowner",

            }
        },
        
        "FunctionName": "demofunctionname",
        "Timeout": ,
        "TracingConfig": {
            "Mode": 
        },
        "Version": "",
        "VpcConfig": {
            "SecurityGroupIds": [
                ""
            ],
            "SubnetIds": [
                "",
                "",
                ""
            ],
            "VpcId": ""
        }
    }

] }

我如何加载 json

data = json.load(open('../fileservice.json'))
df = pd.DataFrame(data["Functions"])

它是如何出现的

    FunctionName                                    Environment
0 demofunctionname      {Variables{"COMMIT_HASH":"djkdkd","SERVICE_OWNER":"serviceownertest"}}

我需要它如何出现

        FunctionName                               COMMIT_HASH       SERVICE_OWNER      
0      demofunctionname                            djkdkd             serviceownertest

一直在尝试爆炸方法，但没有完成工作。非常感谢任何建议或指导。

我不认为这是最好的方法。但这是解决方案

s={
    "Functions": [
    {
        "CodeSha256": "",
        "CodeSize": "",
        "Description": "",
        "Environment": {
            "Variables": {
                "COMMIT_HASH": "test",
                "CodeSha256": "",
                "ECS_LOG_STREAM": "",
                "ELASTIC_SEARCH_DOMAIN_ENDPOINT": "",
                "ENVIRONMENT": "prod",
                "SERVICE_NAME": "testingservicename",
                "SERVICE_OWNER": "testingserviceowner",

            }
        },
        
        "FunctionName": "demofunctionname",
        "Timeout": "" ,
        "TracingConfig": {
            "Mode": ""
        },
        "Version": "",
        "VpcConfig": {
            "SecurityGroupIds": [
                ""
            ],
            "SubnetIds": [
                "",
                "",
                ""
            ],
            "VpcId": ""
        }
    }
] }

import pandas as pd
import json

s = json.dumps(s)
data = json.loads(s)

result={'FunctionName': data["Functions"][0]["FunctionName"], 'COMMIT_HASH': data["Functions"][0]["Environment"]["Variables"]["COMMIT_HASH"], 'SERVICE_OWNER': data["Functions"][0]["Environment"]["Variables"]["SERVICE_OWNER"]}

df = pd.DataFrame(data= [result])
print(df)

注意：我认为你的 json 有问题，我已经在我的解决方案中修复了它。

这是多个“功能”的代码

看看 pd.json_normalize()。这是一个非常好的工具。在你的情况下：

pd.json_normalize(s["Functions"])

将给出以下输出（仅转换后的第一行）：
