如何使用 python 和 jq 从多个值中获取 json 值 select

Question

I have been struggling with json stuff. I have "unit_number" and "key" values and I want to find backing_uuid based on the unit_number and key values. How can I do that with python? I think like this jq query but I've never tried before. I don't know how can I call jq in python.

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

I have json file like this:

{
    "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
        }
    }
}

Answer 1

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

Answer 2

Since.unit_number and.key are already numbers, the jq query would be:

.guest_disk_facts[]
| select(.unit_number==2 and .key == 2002).backing_uuid
