How to convert list to json :

list is :

cords = [ [20.339751164468076, 85.8083048318772], [20.339866852950124, 85.80909340132757]]

json_cords = [
    {
        'lat': 20.339751164468076,
        'lon': 85.8083048318772
    },
    {
        'lat': 20.339866852950124,
        'lon': 85.80909340132757
    }

Answer 1

Use the below dictionary comprehension:

import json
cords = [ [20.339751164468076, 85.8083048318772], [20.339866852950124, 85.80909340132757]]
print(json.dumps([{'lat':x,'lon':y} for x,y in cords],indent=4))

Output:

[
    {
        "lat": 20.339751164468076,
        "lon": 85.8083048318772
    },
    {
        "lat": 20.339866852950124,
        "lon": 85.80909340132757
    }
]
