我正在嘗試從 api 中獲取資訊。如果我理解正確，一旦我使用 json 模塊，我應該得到一個字典，我應該能夠從中提取資訊。
但是無論我使用什么鍵，我都會收到錯誤訊息
import requests
r = requests.get('https://api.mercadolibre.com/sites/MLA/search?q=gt 710 usado &sort=price_asc')
a = r.json()
print(a['title'])
無論我使用什么關鍵字都會出現以下錯誤
Traceback (most recent call last):
File "C:\Users\asdf\Desktop\la\some.py", line 8, in <module>
a["title"]
KeyError: 'title'
uj5u.com熱心網友回復：
title嵌套results在您的 json 物件下。
import requests
r = requests.get('https://api.mercadolibre.com/sites/MLA/search?q=gt 710 usado &sort=price_asc')
a = r.json()
for result in a['results']:
print(result['title'])
輸出
