Conversion d'une Chaîne en Dictionnaire python

Je veux avoir un dictionnaire à partir d' 

 >>> page_detail_string = urllib2.urlopen("http://graph.facebook.com/Ideas4India").read()

Il retourne une chaîne de caractères comme

>>> 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}'

Maintenant, je veux le convertir en dictionnaire que j'ai peut être fait facilement en utilisant de l'ast.literal_eval

>>> 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')

mais je pense qu'il génère cette erreur, en raison de 

"is_published":true

Est il possible que je peux le convertir en dictionnaire par décapage au-dessus de la clé et de la valeur ("is_published":true).

    Utiliser le module json:

    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}

    Aussi, notez que vous pouvez utiliser json.load (au lieu de json.loads) directement sur le fichier de l'objet:

    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}
