Writing data into json file using python

Question

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)

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