JSON has now become a extensively used data format, primarily used to exchange data between different systems, you may say that it is a successor of the XML format in this regard. From small to very large web applications use JSON, some still provide XML format as an option while others don't, a few top web companies using JSON format are Facebook, Flickr, Google GData API, etc. So, let's look and working with JSON in Python programs. Parsing JSON in Python In Python we will be using the json module for parsing JSON, as a sample JSON we would get the contents of http://graph.facebook.com/pradeep.deepz which looks like this: Code: { "id": "703880701", "name": "Pradeep Deepz", "first_name": "Pradeep", "last_name": "Deepz", "link": "http://www.facebook.com/pradeep.deepz", "username": "pradeep.deepz", "gender": "male", "locale": "en_IN" } Code: #!/usr/bin/python import json json_str = """{ "id": "703880701", "name": "Pradeep Deepz", "first_name": "Pradeep", "last_name": "Deepz", "link": "http://www.facebook.com/pradeep.deepz", "username": "pradeep.deepz", "gender": "male", "locale": "en_IN" }""" print json.loads(json_str) print data = json.loads(json_str) print data["name"] The output: Code: {u'username': u'pradeep.deepz', u'first_name': u'Pradeep', u'last_name': u'Deepz', u'name': u'Pradeep Deepz', u'locale': u'en_IN', u'gender': u'male', u'link': u'http://www.facebook.com/pradeep.deepz', u'id': u'703880701'} Pradeep Deepz Create JSON in Python Creating JSON is as easy as decoding, follow the example code below. Code: #!/usr/bin/python import json data = { "names" : ['Anjali','Pradeep'], "Cities" : ['Mumbai','Kolkata'] } ## output print json.dumps(data) ## sort output by keys print json.dumps(data, sort_keys=True) ## pretty printing print json.dumps(data, sort_keys=True, indent=4) The output: Code: {"Cities": ["Mumbai", "Kolkata"], "names": ["Anjali", "Pradeep"]} {"Cities": ["Mumbai", "Kolkata"], "names": ["Anjali", "Pradeep"]} { "Cities": [ "Mumbai", "Kolkata" ], "names": [ "Anjali", "Pradeep" ] }
