you've asked nearly 1000 questions here, you should know by now: you need to show the error you got. — Ned Batchelder, Mar 28 '11 at 12:25

You should use a JSON parser such as the simplejson module rather than using eval:

>>> a = '''{"title":"sss",
"body":"wwww：aaa&nbsp;&nbsp;&nbsp;<a href='#' onclick='logout()' >fff</a>",
"data":{"status":0,"userName":"www","userId":"433"}}'''
>>> import simplejson
>>> parsed_data = simplejson.loads(a)
>>> parsed_data['title']
'sss'

I would also try demjson. this should let you write your json data as a python object and then encode it.

Works fine here. But you should be using json/simplejson to deserialize, not eval().

Dictionaries are accessed as a["title"] in Python, not a.title.

Apart from this, you should use Python's json module instead of eval().
