Converting Python list in JSON

Question

I want to convert a python list into json, here's the input

obj=([{'value1': 'a', 'value2': None, 'value3': 'abc', 'value4': 'xyz', 'value5': 'tes', 'value6': None, 'value7': None, 'value8': 'a'}],
[{'value1': 'b', 'value2': None, 'value3': 'abc', 'value4': 'uyt', 'value5': 'tuy', 'value6': None, 'value7': None, 'value8': 'b'}])

Desired Output:

{ "file": [
   {
    "value1": "a", 
    "value2": None,
    "value3": "abc",
    "value4": "uyt",
    "value5": "tuy",
    "value6": None,
    "value7": None,
    "value8": "a",
   },
   {
    "value1": "b", 
    "value2": None,
    "value3": "abc",
    "value4": "xyz",
    "value5": "tes",
    "value6": None,
    "value7": None,
    "value8": "b",
   }
]
}

PS: I followed some existing issues on StackOverflow, but it's not working for me. Thank you. :)

Answer 1

This should work for any number of lists:

import json

obj = (
    [{
        'value1': 'a', 'value2': None, 'value3': 'abc', 'value4': 'xyz', 'value5': 'tes', 'value6': None, 'value7': None, 'value8': 'a'
    }], 
    [{
        'value1': 'b', 'value2': None, 'value3': 'abc', 'value4': 'uyt', 'value5': 'tuy', 'value6': None, 'value7': None, 'value8': 'b'
    }]
)

result = {'file': []}
for l in obj:
    result['file'].append(l[0])

result_json = json.dumps(result, indent=2)
print(result_json)

Output:

{
  "file": [
    {
      "value1": "a",
      "value2": null,
      "value3": "abc",
      "value4": "xyz",
      "value5": "tes",
      "value6": null,
      "value7": null,
      "value8": "a"
    },
    {
      "value1": "b",
      "value2": null,
      "value3": "abc",
      "value4": "uyt",
      "value5": "tuy",
      "value6": null,
      "value7": null,
      "value8": "b"
    }
  ]
}
