如何获取dict列表的索引并将dict添加到每个索引？

Question

I have a json file with below structure:

{
    "Premier League": {
        "abbreviation": "EN_PR",
        "id": 1.0,
        "seasons": [
            {
                "label": "2019/20",
                "id": 274.0
            },
            {
                "label": "2018/19",
                "id": 210.0
            }
        ]
    },
    "UEFA Champions League": {
        "abbreviation": "EU_CL",
        "id": 2.0,
        "seasons": [
            {
                "label": "Champions League Season 2019/2020",
                "id": 288.0
            },
            {
                "label": "2018/19",
                "id": 214.0
            },
        ]
}

What I'm trying to do is, while iterating, index each season_id , later get info about the season_id by making a request with it to an other data-source and lastly add the info gotten to each seasons_id . So it get's something like this, and do that for each season_id in seasons. Below is an example help you illustrate what I mean by indexing each season id in seasons .

{
        "Premier League": {
            "abbreviation": "EN_PR",
            "id": 1.0,
            "seasons": [
                {
                    "label": "2019/20",
                    "id": 274.0,
                    "teams" :{
                         "Arsenal":{
                             "Players":{}
                                   },

                              }
                },

The question is: How do I Iterate over the the seasons list for each parent key and add info to each season_id?

Below prints each season-id, but I'm not sure how to access them and add info to them.

 for key in parent_key:
    seasons = file[key]['seasons']
    for season in seasons:
        print(season['id'])

Answer 1

If possible, you may find that if you are frequently updating items by id, then parsing your data into the following format is much easier:

leagues = { 
    1: {
        "name": "Premier_League",
        "seasons": { 
            274: {
                "label": "2019/20"
            }
        }
    }
}

Then, given a league_id and a season_id , you can easily access the season associated with it as leagues[league_id]["seasons"][season_id] . You can also update info in that season with:

league_id = 1
season_id = 274
leagues[league_id]["seasons"][season_id]["teams"] = { "Arsenal": { "players": {}}}
print(leagues)

# {1: {'name': 'Premier_League', 'seasons': {274: {'label': '2019/20', 'teams': {'Arsenal': {'players': {}}}}}}}

In general, dicts are good for fast and simple lookup when you know the key that you are trying to look up.
