Question

在 Python 中，我正在尝试解析来自 musixmatch api 的 json 响应，但我无法弄清楚如何访问给定的信息，请帮忙！如有必要，我可以稍后 post JSON 回复，但它有很多文字。

import json
from os.path json, dirname
from musixmatch import Musixmatch

musixmatch = Musixmatch(<api key>)

lyrics = musixmatch.matcher_lyrics_get('Grenade', 'Bruno Mars')


print (lyrics)

for item in jsonLyric['message']:
   for thing in item['body']:
     for stuff in thing['lyrics']:
        print(stuff['lyrics_body'])

这是我用打印（歌词）返回的输出

Answer 1

所以可以看出 JSON 响应是一个字典，它里面有许多其他字典，但我们想要达到的是 body 字典，其中包含 "lyrics_body" 和它的价值。

我们怎么能这样做？其实很简单。在一行中，我们可以继续调用字典并传递包含另一个键的键，例如，我们要访问的第一个字典是整个 JSON 响应，因此我们可以调用 lyrics 变量，其中包含 JSON响应，然后我们传递我们想要访问的密钥在这种情况下"message"，歌词["message"].

print(lyrics["message"]["body"]["lyrics"]["lyrics_body"])

你做的方法也很简单。您只想遍历集成词典中的每个键。

for message in lyrics:
    for body in lyrics[message]:
     if body == "body":
         for lyric in lyrics[message][body]:
             for lyrBod in lyrics[message][body][lyric]:
                 if lyrBod == "lyrics_body":
                     print(lyrics[message][body][lyric][lyrBod])

如您所见，两者是一样的，只是需要更长的时间。
