使用 python 重新格式化 json

Question

I'm receiving json file like below:

[
    {
        "from":"BUS_TYPE_CODE",
        "to":"BUS_TYPE_CODE"
    }
    ,
    {
        "from":"RECORD_TYPE_IDENTIFIER",
        "to":"RECORD_TYPE_IDENTIFIER"
    }
]

But I want to reformat it like below before sending to external teams for processing, Any help would be highly appreciated.!.

[
    {
        "from":["BUS_TYPE_CODE"],
        "to":["BUS_TYPE_CODE"]
    }
    ,
    {
        "from":["RECORD_TYPE_IDENTIFIER"],
        "to":["RECORD_TYPE_IDENTIFIER"]
    }
]

Answer 1

This is a possible solution ( json_obj is your input JSON object):

new_json_obj = [{k: [v] for k, v in d.items()} for d in json_obj]

Answer 2

import json

with open('nameoffile.json') as json_file: 
    data = json.load(json_file) 
  
for dictionary in data:
    for key, value in dictionary.items():
        dictionary[key]=[value]

Than just print it

print(data)

Or write in another file:

f = open("newfile.json", "w")
f.write(json.dumps(data))
f.close()
