[英]Converting a String into Dictionary python
I want to have a dictionary from 我想要一本字典
>>> page_detail_string = urllib2.urlopen("http://graph.facebook.com/Ideas4India").read()
It returns a string like 它返回一个类似的字符串
>>> 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}'
Now i want to convert it to dictionary which i can be easily done by using ast.literal_eval 现在我想将其转换为字典,可以使用ast.literal_eval轻松完成
>>> 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')
but I think it throws this error because of 但我认为这是因为
"is_published":true
Is there any way i can convert it to dictionary by stripping above key and value ("is_published":true). 有什么办法可以通过剥离键和值(“ is_published”:true)将其转换为字典。
Thanks 谢谢
What you get is a json string, you shoule use json.loads to convert to dict 您得到的是一个json字符串,您应该使用json.loads转换为dict
import json
json.loads(page_detail_string)
Use the json
module 使用json
模块
import json
json.loads(page_detail_string)
To read more about the json
module, check out http://docs.python.org/2/library/json.html 要了解有关json
模块的更多信息,请访问http://docs.python.org/2/library/json.html
Use the json module : 使用json模块 :
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.',

Also, note that you can use json.load
(instead of json.loads
) directly on the file object: 另外,请注意,您可以直接在文件对象上使用json.load
(而不是json.loads
):
In [4]: import urllib2
In [5]: json.load(urllib2.urlopen("http://graph.facebook.com/Ideas4India"))
