I would like to convert a json file below:

    [
        {
            "userid": "5275800381",
            "status": "UserStatus.RECENTLY",
            "name": "Ah",
            "bot": false,
            "username": "None"
        },
        {
            "userid": "5824657725",
            "status": "UserStatus.LAST_MONTH",
            "name": "A45",
            "bot": false,
            "username": "None"
        },
        {
            "userid": "5160075986",
            "status": "UserStatus.RECENTLY",
            "name": "CTLA",
            "bot": false,
            "username": "james888"
        }
    ]

into a csv file with more columns and without duplicates as follows:

    username,user id,access hash,name,group,group id,is_bot,is_admin,dc_id,have_photo,phone,elaborated

The output file should be:

    username,user id,access hash,name,group,group id,is_bot,is_admin,dc_id,have_photo,phone,elaborated
    ,5275800381,False,False,False,False,False,False,False,False,False,False
    ,5824657725,False,False,False,False,False,False,False,False,False,False
    james888,5160075986,False,False,False,False,False,False,False,False,False,False

I have tried the following codes:

    import json

    with open('target_user2.json', 'r', encoding='utf-8') as fp:
        target = json.load(fp) #this file contains the json

    with open('members2.csv', 'w', encoding='utf-8') as nf:    # target_userid2.txt or target_userid2.json
        nf.write('username,user id,access hash,name,group,group id,is_bot,is_admin,dc_id,have_photo,phone,elaborated' + 'n')
        for item in target:
            if item['user id'] in [x['user id'] for x in target]:
                if item['username'] != "None":
                    item['username'] == ""
                    record = item['username'] + ',' + item['user id'] + ',' + 'false' + ',' + 'false' + ',' + 'false' + ',' + 'false' + ',' + 'false' + ',' + 'false' + ',' + 'false' + ',' + 'false' + ',' + 'false' + ',' + 'false'
                    nf.write(json.dumps(record).replace('"', '') + 'n')       # write data without ""

it does not work because error is generated by item[‘user id’] (user id with a space not working), but item[‘userid’] works.

How can I fix this?
