JSON

The json library can parse JSON from strings or files. The library parses JSON into a Python dictionary or list. It can also convert Python dictionaries or lists into JSON strings.

Parsing JSON

Take the following string containing JSON data:

json_string = '{"first_name": "Guido", "last_name":"Rossum"}' 

It can be parsed like this:

import json parsed_json = json.loads(json_string) 

and can now be used as a normal dictionary:

print(parsed_json['first_name']) "Guido" 

You can also convert the following to JSON:

d = { 'first_name': 'Guido', 'second_name': 'Rossum', 'titles': ['BDFL', 'Developer'], } print(json.dumps(d)) '{"first_name": "Guido", "last_name": "Rossum", "titles": ["BDFL", "Developer"]}'
