如何使用python和jq从多个值中选择json值

Question

我一直在为json的东西而挣扎。我有“单位号”和“键”值，我想根据单位号和键值找到备份ID。如何使用python实现这一点？我喜欢这个jq查询，但我以前从未尝试过。我不知道如何在python中调用jq

jq .guest_disk_facts[] |  select(any(.attributes[]?; .unit_number=="2" and .key" == "2002")).backing_uuid and output: 9000da43-8471-57a6-8b18-4425a356b3cb

我有这样的json文件：

{
    "changed": false,
    "failed": false,
    "guest_disk_facts": {
        "0": {

            "backing_uuid": "9000da43-8471-57a6-8b18-92381ab3c3f6",
            "key": 2000,
            "unit_number": 0
        },
        "1": {
            "backing_uuid": "9000da43-8471-57a6-8b18-2788c2398ba7",
            "key": 2001,
            "unit_number": 1
        },
        "2": {
            "backing_uuid": "9000da43-8471-57a6-8b18-4425a356b3cb",
            "key": 2002,
            "unit_number": 2
        }
    }
}

for thing in dic['guest_disk_facts']:
    if thing['key'] == key and thing['unit_number'] == unit_number:
        print(thing['backing_uuid'])
        break
