的问题

如何将这个列表对象变成一个漂亮的字典，每个对象有1个标题，1个链接和1个日期？

我希望能够运行：

for item in items:
    print(item['link'], item['title'], item['date'] )

并在每个印刷品上收到1个链接，1个标题和1个日期作为输出。我怀疑zip（）可能会有所帮助，但无法弄明白。

非常感谢任何帮助

Answer 1

您可以使用zip()配对三个列表中的元素：

for link, title, date in zip(items['link'], items['title'], items['date']):

这里没有必要把任何东西变成字典。

演示：

>>> for link, title, date in zip(items['link'], items['title'], items['date']):
...     print(link)
...     print(title)
...     print(date)
...     print('------')
... 
/Detail/2015/02/12/397336/Yemen-collapsing-before-our-eyes
The UN chief calls on the Security Council to take action in halting Yemen's slide toward anarchy.
Thu Feb 12, 2015 6:52PM
------
/Detail/2015/02/12/397337/Bahrainis-pay-price-for-democracy
Nabeel Rajab says Bahraini people are paying a heavy price for democratic and human rights values.
Thu Feb 12, 2015 6:48PM
------
# etc.

您也可以为每个循环迭代重建字典：

for values in zip(*items.values()):
    item = dict(zip(items.keys(), values))
    print(item)

这取决于dict.keys()和dict.values()按匹配顺序生成结果的事实。

演示：

>>> for values in zip(*items.values()):
...     item = dict(zip(items.keys(), values))
...     print(item)
... 
{'date': 'Thu Feb 12, 2015 6:52PM', 'link': '/Detail/2015/02/12/397336/Yemen-collapsing-before-our-eyes', 'title': "The UN chief calls on the Security Council to take action in halting Yemen's slide toward anarchy."}
{'date': 'Thu Feb 12, 2015 6:48PM', 'link': '/Detail/2015/02/12/397337/Bahrainis-pay-price-for-democracy', 'title': 'Nabeel Rajab says Bahraini people are paying a heavy price for democratic and human rights values.'}
{'date': 'Thu Feb 12, 2015 6:40PM', 'link': '/Detail/2015/02/12/397301/Russia-Venezuela-to-hold-joint-drills', 'title': 'Russia and Venezuela plan to hold joint military drills in the Caribbean Sea, a source says.'}
# etc.

Answer 2

我建议选择Martijn Pieters＆＃39;解决方案，但如果你坚持使用，你可以这样做：

items = []
for i in range(len(myDict["title"])):
    items.append({"title":myDict["title"][i], "link":myDict["link"][i], "date":myDict["date"][i]})

Answer 3

这是你的意思吗？

items = [{"title" : items["title"][i],
          "link" : items["link"][i],
          "date" : items["date"][i]}

         for i in range(len(items["title"]))]


import pprint
pprint.pprint(items)

把名单变成dict
