Cannot parse JSON data returned between [{ and }] Python

Question

Here's where I'm starting from:

url = 'https://api.example.com/'
bearer_token = 'my_token'

result = requests.get(url,headers={'Content-Type':'application/json','Authorization': 'Bearer {}'.format(bearer_token)}).json()
print(result[3])

When I print the type of result my JSON results produce, I get a 'list', but I can't parse through it the way one normally would a list. For example, I can't access keys behind [ and {. These areas seem to be treated differently when I try to parse data from them. Some values are accessible by [index]['key'], others are not.

Here's a snippet of my JSON output when I print(result[3]):

{'created_at': 'Wed Oct 1 10:20:16 +0000 2021', 'id': 1448292507, 'id_str': '1448817927', 'text': 'Lorem ipsum data data data', 'truncated': True, 'entities': {'hashtags': [{'text': 'RedLife', 'indices': [90, 101]}, {'text': 'NS18', 'indices': [102, 107]}], 'symbols': [], 'user_ment': [{'n_name': 'name_1', 'name': 'name_2', 'id': 5232, 'id_str': '32', 'indices': [12, 10]}, {'n_name': 'Lorem', 'name': 'Lorem', 'id': 1372, 'id_str': '72', 'indices': [10, 17]}, {'n_name': 'TV', 'name': 'TV', 'id': 3576, 'id_str': '76', 'indices': [55, 60]}], 'urls': [{'url': 'https://website.com', 'expanded_url': 'https://website'...}

When I print(result[3]['created_at']), I get Wed Oct 1 10:20:16 +0000 2021. Great!

When I try other keys in the list I get KeyErrors.

What do I need to do to my JSON data in order to pull all the data I need? And in the case where there exists multiple instances of the same 'key', how do I retrieve the 'value' I'm looking for? Do I just append the index I want like this: print(result[3]['n_name'][0])?

To access n_name, you're missing 'entities' and 'user_ment' levels in the dict, then you have a list, then again a list

result = [
    {},
    {},
    {},
    {'created_at': 'Wed Oct 1 10:20:16 +0000 2021', 'id': 1448292507,
     'id_str': '1448817927',
     'text': 'Lorem ipsum data data data', 'truncated': True,
     'entities': {
         'hashtags': [{'text': 'RedLife', 'indices': [90, 101]}, {'text': 'NS18', 'indices': [102, 107]}],
         'symbols': [],
         'user_ment': [
             {'n_name': 'name_1', 'name': 'name_2', 'id': 5232, 'id_str': '32', 'indices': [12, 10]},
             {'n_name': 'Lorem', 'name': 'Lorem', 'id': 1372, 'id_str': '72', 'indices': [10, 17]},
             {'n_name': 'TV', 'name': 'TV', 'id': 3576, 'id_str': '76', 'indices': [55, 60]}
         ],
         'urls': [{'url': 'https://website.com', 'expanded_url': 'https://website'}]
     }}
]

x = result[3]['entities']['user_ment'][0]['n_name']
print(x)  # name_1

x = result[3]['entities']['user_ment'][1]['n_name']
print(x)  # Lorem
