如果需求是m，那么如何从json获取2个键

Question

我在做一个项目，它列出了Twitch上的前5个直播雷管。要创建这个列表，我想从状态为skyblock或moded且broadcast_platform为live的流中获取显示名称和查看器。但我还没弄明白怎么做。我是新来Python所以请不要烤我，如果真的很容易；）。提前谢谢你的帮助

我试过使用

names = [x['display_name'] for x in data['streams'][0]['channel'] if any(s in x.get('status', '').lower() for s in ['skyblock', 'modded']) ]

但这会产生以下错误：AttributeError: 'str' object has no attribute 'get'我不知道如何添加一种方法来检查broadcast_platform是否是live

Answer 1

要根据频道状态获取显示名称：

names = [x['channel']['display_name'] for x in data['streams'] if any(s in x['channel'].get('status', '').lower() for s in ['skyblock', 'modded'])] 

根据频道状态和广播平台获取显示名称：

names = [x['channel']['display_name'] for x in data['streams'] if any(s in x['channel'].get('status', '').lower() for s in ['skyblock', 'modded']) and x['broadcast_platform'] == 'live']
