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"]}'
