Json Array 按 id 拉取数据

Question

好的，所以我正在为英雄联盟开发一个小应用程序，并且我正在尝试使用他们的 api 来获取球员数据。我想展示他们的前 3 名使用过的英雄，并告诉他们一些关于他们的信息。我可以做到这一点，但我很难通过 ID 来获得冠军的名字。我有一个看起来像这样的 json 数组文件。我只包括其中的几个，因为对于每个英雄来说都相当长。

我可以通过 API 提取玩家最喜欢的 3 个英雄的 ID，但我需要使用该 ID 从 Json 中提取英雄名称。因此，例如，如果玩家最喜欢的冠军 id 是 266，我需要在 json 中搜索等于 266 的键，然后返回 json 对象，以便我可以从中提取名称。我了解应该发生的事情，但一直无法提出工作代码来执行此操作。

如果您的 JSON 字符串化：

import json

def find_name(player_key, data):
    matches = [player['name'] for player in data if player.get('key') == player_key]
    return matches[0] if matches else None

json_response = '....'
data = json.loads(json_response)
player_name = find_name(266, data)
