JSON
|
|
====
|
|
|
|
The `json <https://docs.python.org/2/library/json.html>`_ library can parse JSON from strings or files. When parsing, the library converts the JSON into a Python dictionary or list. It can also parse Python dictionaries or lists into JSON strings.
|
|
|
|
Parsing JSON
|
|
------------
|
|
|
|
Take the following string containing JSON data:
|
|
|
|
.. code-block:: python
|
|
|
|
json_string = '{"first_name": "Guido", "last_name":"Rossum"}'
|
|
|
|
It can be parsed like this:
|
|
|
|
.. code-block:: python
|
|
|
|
import json
|
|
parsed_json = json.loads(json_string)
|
|
|
|
and can now be used as a normal dictionary:
|
|
|
|
.. code-block:: python
|
|
|
|
print(parsed_json['first_name'])
|
|
"Guido"
|
|
|
|
You can also convert a the following to JSON:
|
|
|
|
.. code-block:: python
|
|
|
|
d = {
|
|
'first_name': 'Guido',
|
|
'second_name': 'Rossum',
|
|
'titles': ['BDFL', 'Developer'],
|
|
}
|
|
|
|
print(json.dumps(d))
|
|
'{"first_name": "Guido", "last_name": "Rossum", "titles": ["BDFL", "Developer"]}'
|
|
|
|
|
|
simplejson
|
|
----------
|
|
|
|
`simplejson <https://simplejson.readthedocs.org/en/latest/>`_ is the externally maintained development version of the json library.
|
|
|
|
simplejson mimics the json standard library, it is available so that developers that use an older version of python can use the latest features available in the json lib.
