Remove objects in nested json response python

Question

This json file has nested "dbg_info","status","start_element","num_elements" etc as object.I want to recursively go through json and recursivily remove objects with the name mentioned in this list.["dbg_info","status","start_element","num_elements"].In python.

My Json:

{
    "status": "OK",
    "start_element": 0,
    "num_elements": 100,
   
        }
    ]
}

How to remove nested json elements?.I am not able to set the logic for the same. Thankyou

You can use recursive function

import json

d = json.loads(json_data)
lst = ["dbg_info","status","start_element","num_elements"]

def fun(d, lst=[]):
    if isinstance(d, dict):
        for k, v in list(d.items()):
            d.pop(k) if k in lst else fun(v)
    elif isinstance(d, list):
        map(fun, d)

fun(d, lst)

Thankyou very much.What should i pass in 'd' and function is not returning anything. – Pravin Mishra Sep 09 '20 at 03:07
plus if last element is removed ',' will be present. – Pravin Mishra Sep 09 '20 at 03:07
@pravinmishra updated the answer check now. and what last element why comma is important? – deadshot Sep 09 '20 at 03:11
Got it but its returning none. – Pravin Mishra Sep 09 '20 at 08:10
@pravinmishra there is no need of return the changes made in the function reflect in the dictionary `d` so need of `retutn` – deadshot Sep 09 '20 at 09:15
