How to add data to a already existing json object without overwriting existing data-CodePudding

I have a json object in the form of a dictionary that i make outside of a function. I make a baseline for what the data inside the json object and its keys. What i am trying to do is to save the data i have collected in the function to the json object. I am very unsure on how i add that new data to the json data without overwriting any existing data already present in the json object.

Something i have tried to do is load the json object i am trying to update by doing:

    import json
    data = json.loads(json_obj)

However, when i do this, it throws me an error when assigning new data to it.

TypeError: the JSON object must be str, bytes or bytearray, not dict

This is the json object from before.

    {
        "text": "test text",
        "created_at": "some date",
        "entity": "most_common_entity",
        "username": "someuser",
        "tweet_id": "coolid",
        "hashtags": "#coolndat"
    }

And the way i am attempting to add data to it is by doing:


    json_obj["text"] = row["text"]
    json_obj["created_at"] = row["created_at"]
    json_obj["entity"] = most_common_entity
    json_obj["username"] = row["username"]
    json_obj["tweets_id"] = row["id"]
    json_obj["hashtags"] = row["hashtags"]

It would be amazing if anyone would be able to help my solve my problem.

The end goal would be for the json object to look something like this:

    {
        {
            "text": "test text",
            "created_at": "some date",
            "entity": "most_common_entity",
            "username": "someuser",
            "tweet_id": "coolid",
            "hashtags": "#coolndat"
        },
        {
            "text": "Text two",
            "created_at": "12/5/3042",
            "entity": "ORG",
            "username": "cooluser3",
            "tweet_id": "nice",
            "hashtags": "#verysickhashtag"
        }
    }

CodePudding user response：

The result that you expect to get is a set type, not a dict. Here is an example how you could do that using list.

In [7]: not_a_json_just_a_python_dict =     {
   ...:         "text": "test text",
   ...:         "created_at": "some date",
   ...:         "entity": "most_common_entity",
   ...:         "username": "someuser",
   ...:         "tweet_id": "coolid",
   ...:         "hashtags": "#coolndat"
   ...:     }

In [8]: list_of_dicts = [not_a_json_just_a_python_dict]

In [9]: list_of_dicts.append({
   ...:             "text": "test text",
   ...:             "created_at": "some date",
   ...:             "entity": "most_common_entity",
   ...:             "username": "someuser",
   ...:             "tweet_id": "coolid",
   ...:             "hashtags": "#coolndat"
   ...:         })

In [10]: list_of_dicts
Out[10]:
[{'text': 'test text',
  'created_at': 'some date',
