Python has a built in module named 'json'. You can use it to parse json data.
Since you have your json data in a file all you have to do is read the file and parse it using json module.
Also you can make the output pretty by using the pprint method.
You can do it like this:
from pprint import pprint
data = json.load(open('data.json'))
