python - 遍历 JSON - 需要逻辑来计算值的总和

Question

我正在尝试从下面的 JSON 中获取键值 number 的总和。

总和 = 193(21+52+52+68)

我将在这里使用循环而不是直接访问 - response['jobs']['0']['lastBuild']['number']。任何人都可以提供逻辑吗？任何编程语言都可以。

{
"_class": "hudson.model.Hudson",
"jobs": [
    {
        "_class": "org.jenkinsci.plugins.workflow.job.WorkflowJob",
        "name": "ADP-CHINA-IT",
        "lastBuild": {
            "_class": "org.jenkinsci.plugins.workflow.job.WorkflowRun",
            "number": 21
        }
    },
    {

            "name": "A",

                        "number": 52
                    }
                },

                            }
                        }
                    ]

python :

def sum_(s, dict_):
    return s + reduce(sum_, dict_.get("jobs", []), 0) + dict_.get("lastBuild", {}).get("number", 0)


reduce(sum_, response["jobs"], 0)
