如何从Python中的嵌套数据结构中提取特定数据 [{“单词”：“意思”，“音标”：[{“文本”：“/”miːnɪŋ/”，“音频”：https://lex-audio.useremarkable.com/mp3/meaning_gb_1.mp3“}]，“含义”：[{“词类”：“名词”，“定义”：[{“定义”：“是什么？” '是指单词、文本、概念或' “行为”，“同义词”：[“定义”，“意义”，“解释”，“外延”，“内涵”，“解释”，“阐释”，“解释”]，“示例”：“例子” 印度语的意思是“突破” “释放”'}]}，{“言语的一部分”：“形容词”，“定义”：[{“定义”：“有意” “传达非直接的信息” “表达的”、“同义词”：[“有意义的”、“有意义的”、“尖锐的”、“雄辩的”、“表达的”、“怀孕的”、“说话的”、“告密的”、“透露的”、“暗示的”]}]]

这是格式

我想摘录：

"meanings":[{"partOfSpeech":"noun","definitions":[{"definition":"A single distinct meaningful element of speech or writing, used with others (or sometimes alone) to form a sentence and typically shown with a space on either side when written or printed.",

我可以用Python怎么做。

我相信这就是您想要的

import json
data = ['[{"word":"meaning","phonetics":[{"text":"/ˈmiːnɪŋ/","audio":"https://lex-audio.useremarkable.com/mp3/meaning_gb_1.mp3"}],"meanings":[{"partOfSpeech":"noun","definitions":[{"definition":"What '  'is meant by a word, text, concept, or '  'action.","synonyms":["definition","sense","explanation","denotation","connotation","interpretation","elucidation","explication"],"example":"the '  'meaning of the Hindu word is ‘breakthrough, '  'release’"}]},{"partOfSpeech":"adjective","definitions":[{"definition":"Intended '  'to communicate something that is not directly '  'expressed.","synonyms":["meaningful","significant","pointed","eloquent","expressive","pregnant","speaking","telltale","revealing","suggestive"]}]}]}]']
json_data = json.loads(data[0])
meanings = json_data[0]['meanings']
print(meanings)
# [{'partOfSpeech': 'noun', 'definitions': [{'definition': 'What is meant by a word, text, concept, or action.', 'synonyms': ['definition', 'sense', 'explanation', 'denotation', 'connotation', 'interpretation', 'elucidation', 'explication'], 'example': 'the meaning of the Hindu word is ‘breakthrough, release’'}]}, {'partOfSpeech': 'adjective', 'definitions': [{'definition': 'Intended to communicate something that is not directly expressed.', 'synonyms': ['meaningful', 'significant', 'pointed', 'eloquent', 'expressive', 'pregnant', 'speaking', 'telltale', 'revealing', 'suggestive']}]}]
