如何從JSON響應中提取特定部分？

我有這樣如何從JSON響應中提取特定部分？

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

這個代碼給了我這樣的：

[ 
    { 
     "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"

    } 
]

所有我想要做的就是從響應中的每個「part_of_speech」值，並將其推入清單，但我無法弄清楚如何做到這一點。

我沒有成功嘗試解析和python堅持這實際上是一個列表。

考慮縮進你JSON以提高可讀性。 –

如果Python堅持它是一個列表，它是這樣做的 - 有一個原因 - 在這種情況下，主要原因是它*是*列表，*包含* JSON對象。 – n1c9

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

#prints 'noun'

我現在覺得自己像個白癡！謝謝您的回答。 –

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

noun 
noun 
noun 
noun 
noun 
noun
