在Python中访问嵌套字典中键的第二个实例

Question

所以我利用GMusicAPI来尝试与googleplaymusic交互（我使用MobileClient视图）。不幸的是，它只在Python中，一种我从未使用过的语言。我正在运行一个搜索，它将搜索给定的艺术家。我遇到的问题是，有些艺术家，我想要的艺术家并不是第一个结果。在

我的解决方案是只搜索（此搜索返回一个字典）前5-10位艺术家，然后循环搜索，直到字典键中的名称与搜索查询匹配。在

这是我从搜索中得到的词典的一部分。这就是"artist_hits"部分。在

我的问题是如何访问超过第一个"artist"键的内容？我需要从中得到"name"和{}的值。我给第一个打电话。在

{cd5}

而且效果很好。但是，我试图像这样访问这个键的第二个实例

ArtistSearch['artist_hits'][0]['artist'][1]['name']

但它不起作用。任何帮助都将不胜感激。在

Answer 1

我想你的愿望是：

ArtistSearch['artist_hits'][1]['artist']['name']
#                         -^ -

因为ArtistSearch['artist_hits']是列表，所以您需要第二个字典[1]，并在其中添加{}字段
