python json how to write data one under the other instead of side by side-CodePudding

        self.channel_ticket = await category.create_text_channel(f'övgü-{user.name}',  overwrites=overwrites)

        with open('data.json', 'a ') as f:
            f.seek(0)
            json.dump(str(user_id), f, indent = 4 )

here, it writes user ID that created channel.

Output :

"332115091338297344""323516141777715202"

it writes the ID of more than one user, but how can I make it type from one under the other instead of side by side

CodePudding user response：

As quamrana say, json is a specific format where you can't just add a simple string.

A good way to store id in json format shoul be to create an array of id in your json like that :

{
    "ids": [
        1,
        2,
        3
    ]
}

To do that init your json file with the id's array empty. Then in python, get the array, append new id and rewrites all the file.

new_id = 444
with open('data.json', 'r ') as f:
    # read json datas
    json_datas = json.load(f)
    # get ids array
    ids = json_datas["ids"]
    # add new id    
    ids.append(new_id)
    # rebuild our json
    json_new_datas = json.dumps({"id":ids})
    f.seek(0)
    # write json into file
    f.write(json_new_datas)
