Convert JSON string to dict using Python
提问by Frias
I'm a little bit confused with JSON in Python. To me, it seems like a dictionary, and for that reason I'm trying to do that:
我对 Python 中的 JSON 有点困惑。对我来说，它似乎是一本字典，因此我试图这样做：
{
"glossary":
{
"title": "example glossary",
"GlossDiv":
{
"title": "S",
"GlossList":
{
"GlossEntry":
{
"ID": "SGML",
"SortAs": "SGML",
"GlossTerm": "Standard Generalized Markup Language",
"Acronym": "SGML",
"Abbrev": "ISO 8879:1986",
"GlossDef":
{
"para": "A meta-markup language, used to create markup languages such as DocBook.",
"GlossSeeAlso": ["GML", "XML"]
},
"GlossSee": "markup"
}
}
}
}
}
But when I do print dict(json), it gives an error.
但是当我这样做时print dict(json)，它会出错。
How can I transform this string into a structure and then call json["title"]to obtain "example glossary"?
如何将此字符串转换为结构，然后调用json["title"]以获取“示例词汇表”？

use simplejson or cjson for speedups
使用 simplejson 或 cjson 进行加速
import simplejson as json
json.loads(obj)
or
cjson.decode(obj)

If you trust the data source, you can use evalto convert your string into a dictionary:
如果您信任数据源，则可以使用eval将您的字符串转换为字典：
eval(your_json_format_string)
eval(your_json_format_string)
Example:
例子：
>>> x = "{'a' : 1, 'b' : True, 'c' : 'C'}"
>>> y = eval(x)
>>> print x
{'a' : 1, 'b' : True, 'c' : 'C'}
>>> print y
{'a': 1, 'c': 'C', 'b': True}
>>> print type(x), type(y)
<type 'str'> <type 'dict'>
>>> print y['a'], type(y['a'])
1 <type 'int'>
>>> print y['a'], type(y['b'])
1 <type 'bool'>
>>> print y['a'], type(y['c'])
1 <type 'str'>
