[英]Converting a String into Dictionary python
我想要一本字典
>>> page_detail_string = urllib2.urlopen("http://graph.facebook.com/Ideas4India").read()
它返回一個類似的字符串
>>> page_detail_string
'{"about":"Ideas for development of India","category":"Community","description":"Platform where you can discuss and share your ideas which you think might help in betterment of our country.\\nPlease respect other community members and do not talk politics here.","is_published":true,"talking_about_count":0,"username":"Ideas4India","were_here_count":0,"id":"250014455083430","name":"Ideas 4 India","link":"http:\\/\\/www.facebook.com\\/Ideas4India","likes":23}'
現在我想將其轉換為字典,可以使用ast.literal_eval輕松完成
>>> import ast
>>> dict_page = ast.literal_eval(page_detail_string)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/ast.py", line 80, in literal_eval
return _convert(node_or_string)
File "/usr/lib/python2.7/ast.py", line 63, in _convert
in zip(node.keys, node.values))
File "/usr/lib/python2.7/ast.py", line 62, in <genexpr>
return dict((_convert(k), _convert(v)) for k, v
File "/usr/lib/python2.7/ast.py", line 79, in _convert
raise ValueError('malformed string')
但我認為這是因為
"is_published":true
有什么辦法可以通過剝離鍵和值(“ is_published”:true)將其轉換為字典。
謝謝
您得到的是一個json字符串,您應該使用json.loads轉換為dict
import json
json.loads(page_detail_string)
使用json
模塊
import json
json.loads(page_detail_string)
要了解有關json
模塊的更多信息,請訪問http://docs.python.org/2/library/json.html
使用json模塊 :
In [1]: s = '{"about":"Ideas for development of India","category":"Community","description":"Platform where you can discuss and share your ideas which you think might help in betterment of our country.\\nPlease respect other community members and do not talk politics here.","is_published":true,"talking_about_count":0,"username":"Ideas4India","were_here_count":0,"id":"250014455083430","name":"Ideas 4 India","link":"http:\\/\\/www.facebook.com\\/Ideas4India","likes":23}'
In [2]: import json
In [3]: json.loads(s)
Out[3]:
{u'about': u'Ideas for development of India',
u'category': u'Community',
u'description': u'Platform where you can discuss and share your ideas which you think might help in betterment of our country.\nPlease respect other community members and do not talk politics here.',
u'id': u'250014455083430',
u'is_published': True,
u'likes': 23,
u'link': u'http://www.facebook.com/Ideas4India',
u'name': u'Ideas 4 India',
u'talking_about_count': 0,
u'username': u'Ideas4India',
u'were_here_count': 0}
另外,請注意,您可以直接在文件對象上使用json.load
(而不是json.loads
):
In [4]: import urllib2
In [5]: json.load(urllib2.urlopen("http://graph.facebook.com/Ideas4India"))
Out[5]:
{u'about': u'Ideas for development of India',
u'category': u'Community',
u'description': u'Platform where you can discuss and share your ideas which you think might help in betterment of our country.\nPlease respect other community members and do not talk politics here.',
u'id': u'250014455083430',
u'is_published': True,
u'likes': 23,
u'link': u'http://www.facebook.com/Ideas4India',
u'name': u'Ideas 4 India',
u'talking_about_count': 0,
u'username': u'Ideas4India',
u'were_here_count': 0}
