如何在Python中对JSON的输出进行排序

Question

如何按字母顺序输出标题？我要打印“娱乐”然后“信息”。你知道吗

注意：这只是一个示例。我正在使用的json文件有更多的标题

>>> import json >>> field = json.loads('{"js":[{"id":"1","title":"information","number":"1","alias":"information"},{"id":"2","title":"entertainments","number":"2","alias":"entertainments"}],"text":""}') >>> for data in field['js']: ... print data['title'] ... information entertainments

Answer 1

使用键对列表排序：

field['js'].sort(key=lambda k: k['title'])

有关详细信息，请参见How do I sort a list of dictionaries by values of the dictionary in Python?

Answer 2

单向：

>>> for data in sorted(field['js']):
...   print data['title']
... 
entertainments
information
