我正在使用 Stack Overflow api 通過傳遞查詢來搜索問題。
我正在使用以下代碼：
def search_query_stackoverflow(query):
title_search_string = query
SITE = StackAPI('stackoverflow')
questions = SITE.fetch('search/advanced', title = title_search_string)
print(questions)
我想獲得或能夠操縱關鍵“專案”中的所有內容。例如，我想獲取關鍵標題和鏈接。我以 dict 格式得到以下內容。我知道它是元組的字典，但我無法從元組內的字典中獲取鍵標題和鏈接。

uj5u.com熱心網友回復：
itemsdict 中鍵的值的型別是串列，因此您可以使用串列理解來操作它。例如 -
questions['items'] = [{'link':item['link']} for item in questions['items']
