JSON is a syntax for storing and exchanging data.
JSON is text, written with JavaScript object notation.
JSON in Python
Python has a built-in package called json, which can be use to work with JSON data.
Example
Import the json module:
import json
Parse JSON – Convert from JSON to Python
If you have a JSON string, you can parse it by using the json.loads() method.
The result will be a Python dictionary.
Example
Convert from JSON to Python:
import json # some JSON: x = '{ "name":"John", "age":30, "city":"New York"}' # parse x: y = json.loads(x) # the result is a Python dictionary: print(y["age"])
Output
Convert from Python to JSON
If you have a Python object, you can convert it into a JSON string by using the json.dumps() method.
Example
Convert from Python to JSON:
import json # a Python object (dict): x = { "name": "John", "age": 30, "city": "New York" } # convert into JSON: y = json.dumps(x) # the result is a JSON string: print(y)
Output
You can convert Python objects of the following types, into JSON strings:
- dict
- list
- tuple
- string
- int
- float
- True
- False
- None
Example
Convert Python objects into JSON strings, and print the values:
import json print(json.dumps({"name": "John", "age": 30})) print(json.dumps(["apple", "bananas"])) print(json.dumps(("apple", "bananas"))) print(json.dumps("hello")) print(json.dumps(42)) print(json.dumps(31.76)) print(json.dumps(True)) print(json.dumps(False)) print(json.dumps(None))
Output
