Writing data into json file using python

With the following python code :

    import fnmatch
    import os
    import json

    data = []
    for file in os.listdir('./images'):
        if fnmatch.fnmatch(file, '*.jpg'):
            data.append(file)
    with open('asd.json', 'w') as f:
        json.dump({'data' : {"name": data}},f,sort_keys = True, indent = 4, 
            ensure_ascii = False)

I am getting the following json output in file asd.json:

{
    "data": {
        "name": [
            "got01.jpg",
            "got02.jpg"
        ]
    }
}

But I want my json output in asd.json as :

{
  "data": [
    {
      "name": "got01.jpg"
    },
    {
      "name": "got02.jpg"
    }
  ]
}

Can you suggest a better approach to get the output in desired structure?

Try

json.dump({'data' : [{"name": x} for x in data]},f,sort_keys = True, indent = 4, ensure_ascii = False)

Full code:

import fnmatch
import os
import json

data = []
for file in os.listdir('./images'):
    if fnmatch.fnmatch(file, '*.jpg'):
        data.append(file)
with open('asd.json', 'w') as f:
    json.dump({'data' : [{"name": x} for x in data]},f,sort_keys = True, indent = 4, 
        ensure_ascii = False)
