如何通过键从 json 中获取值作为 python 中的变量

Question

I am trying for fetching some data from below json

[
    {
        "company": "XYZ",
        "companyAddress": "PQR",
        "staffDetails": [
            {
                "employeeCount": {
                    "jobLevel1": "9",
                    "jobLevel2": "10",
                    "jobLevel3": "11"
                },
                "otherStaff": {
                    "jobLevel1": "99",
                    "jobLevel2": "100"
                }
            }
        ]
    },
    
    {
        "company": "XXX",
        "companyAddress": "YYY",
        "staffDetails": [
            {
                "employeeCount": {
                    "jobLevel1": "9",
                    "jobLevel2": "10",
                    "jobLevel3": "11"
                },
                "otherStaff": {
                    "jobLevel1": "99",
                    "jobLevel2": "100"
                }
            }
        ]
    }
]

What data i want to fetch is configurable. eg below 2 details i want.

config.properties

[details]
reqparameters=staffDetails.employeeCount.joblevel1 ,staffDetails.otherStaff.joblevel2

myPython code is like below-

   import configparser
    import json
    config=configparser.RawConfigParser()
    config.read('config.properties')
    parameters=config.get('details','reqparameters')
    splitedValue=responseDetails.split(",")
    resp='''    [
            {
                "company": "XYZ",
                "companyAddress": "PQR",
                "staffDetails": [
                    {
                        "employeeCount": {
                            "jobLevel1": "9",
                            "jobLevel2": "10",
                            "jobLevel3": "11"
                        },
                        "otherStaff": {
                            "jobLevel1": "99",
                            "jobLevel2": "100"
                        }
                    }
                ]
            },
            
            {
                "company": "XXX",
                "companyAddress": "YYY",
                "staffDetails": [
                    {
                        "employeeCount": {
                            "jobLevel1": "9",
                            "jobLevel2": "10",
                            "jobLevel3": "11"
                        },
                        "otherStaff": {
                            "jobLevel1": "99",
                            "jobLevel2": "100"
                        }
                    }
                ]
            }
        ]'''
    #x = json.loads(resp, object_hook=lambda d: SimpleNamespace(**d))
    x = json.loads(resp)
    
    for property in splitedValue:
     for jNode in x:
       print(jNode[property])
       print(jNode.property)

tried both the ways print(jNode[property]) & print(jNode.property) along with x = json.loads(resp, object_hook=lambda d: SimpleNamespace(**d)) but it's not working. As my input is configurable i can't harcode that with jNode so need it with dynamically using variable property which i am reading from properties file

This is not how JSON handling works in Python to access the sections you need would use:

jNode['staffDetails'][0]['employeeCount']['jobLevel1']

There is an issue in your data the config file says joblevel1 but the key in the json is jobLevel1 (capital L) The other issue you are going to have here is that staffDetails is a list so do you know that it will always be one element? or could it be more?

Doing this directly in Python would be messy eg

In [564]:
    ...: for config in splitedValue:
    ...:     for company in x:
    ...:         data = company
    ...:         for node in config.split('.'):
    ...:             if isinstance(data, type(list)):
    ...:                 data = data[0]
    ...:             data = data[node]
    ...:         print(f"company: {company['company']} {config}: {data}")
    ...:
company: XYZ staffDetails.employeeCount.jobLevel1: 9
company: XXX staffDetails.employeeCount.jobLevel1: 9
company: XYZ staffDetails.otherStaff.jobLevel2: 100
company: XXX staffDetails.otherStaff.jobLevel2: 100

Personally I would look at making changes to the JSON and the config file to make them work better together
