如何從JSON響應中提取特定部分？

Question

我有類似的代碼

import requests
dict_api = "http://api.pearson.com/v2/dictionaries/entries?headword="
r = requests.get(dict_api + word)
results = r.json()["results"]

這給了我這個：

[

        "senses": [
            {
                "translation": "\\u6c99\\u62c9\\uff0c\\u8272\\u62c9\\uff0c\\u6c99\\u5f8b\\u3014\\u7528\\u751f\\u83dc\\u3001\\u9ec3\\u74dc\\u3001\\u756a\\u8304\\u7b49\\u751f\\u7684\\u852c\\u83dc\\u4f5c\\u539f\\u6599\\u7684\\u6dbc\\u62cc\\u83dc\\u3015"

        "headword": "word salad",
        "id": "cqAJqE3gvE"
    }
]

我要做的就是從響應中獲取每個“ part_of_speech”值並將其推送到列表中，但是我不知道該怎么做。

我嘗試解析失敗，並且python堅持認為這實際上是一個列表。

Answer 1

print(results[0]['part_of_speech'])

#prints 'noun'

Answer 2

for i in range(len(results)):
    print(results[i]['part_of_speech'])

noun
noun
