古怪模式开启

我下载了 Jeopardy 问题的 200k Q/A。我认为插入一些琐事机器人会很有趣。无论如何，它的大小为 50M，我可以看到没有换行符。

 {"category": "EVERYBODY TALKS ABOUT IT...", "air_date": "2004-12-31", "question": "'The city of Yuma in this state has a record average of 4,055 hours of sunshine each year'", "value": "$200", "answer": "Arizona", "round": "Jeopardy!", "show_number": "4680"},

对于列表中的每个字典，获取'question'和'answer'键：

for l in d:
    print l['question'], l['answer']

输出：

'For the last 8 years of his life, Galileo was under house arrest for espousing this man's theory' Copernicus
'No. 2: 1912 Olympian; football star at Carlisle Indian School; 6 MLB seasons with the Reds, Giants & Braves' Jim Thorpe
'The city of Yuma in this state has a record average of 4,055 hours of sunshine each year' Arizona
