Very simple:
import json
data = json.loads('{"one" : "1", "two" : "2", "three" : "3"}')
print(data['two']) # or `print data['two']` in Python 2
For URL or file, use json.load(). For string with .json content, use json.loads().
#! /usr/bin/python
import json
# from pprint import pprint
json_file = 'my_cube.json'
cube = '1'
with open(json_file) as json_data:
data = json.load(json_data)
# pprint(data)
print "Dimension: ", data['cubes'][cube]['dim']
print "Measures: ", data['cubes'][cube]['meas']
» pip install ijson
