Simplejson strange behavior

Question

So In python I make a dictionary in JSON structure

>>> a = {"name":'nikhil',"age":25}

Now I check if a is a Valid JSON using http://jsonlint.com/ . I get it's valid.

Now I do :

>>> b = simplejson.dumps(a)
>>> b= '{"age": 25, "name": "nikhil"}'

Now I do:

>>> c = simplejson.loads(b)
>>> c = {'age': 25, 'name': 'nikhil'}

Now I check if c is a Valid JSON I get error.

Why is Simplejson is not able to convert JSON string back to valid JSON? when I started with a valid JSON only?

You are confusing JSON with Python here. b is a JSON-formatted string, c is a Python object .

Python syntax just happens to look a lot like JSON (JavaScript) in that respect.

• Python strings can use either ' or " , depending on the contents; JSON always uses " . You entered a using double quotes for the keys, single quotes for the one string value; if you asked Python to echo it back for you you'll find it'll be shown with only single quotes.

• Python booleans are True or False , JSON uses true and false .

• The JSON 'empty' value is null , Python uses None instead.

See the Encoders and Decoders section of the json module for an overview how JSON and Python objects are mapped.
