json handling in python code example

Example 1: print json python

import json

uglyjson = '{"firstnam":"James","surname":"Bond","mobile":["007-700-007","001-007-007-0007"]}'

#json.load method converts JSON string to Python Object
parsed = json.loads(uglyjson)

print(json.dumps(parsed, indent=2, sort_keys=True))

Example 2: python json file operations

import json # Imports the json file that we need
with open("jsonfile.json", "r") as jsonFile: # Opens Json file for reading
	data = json.load(jsonFile) # Reads Json file using json.load() method
'''
Example Json File:
[{"name": "Bill", "age": 20},
{"name": "Mary", "age": 31},
{"name": "Jake", "age": 19}]
'''
data[1]["age"] = 32 # Alters data variable
''' 
Now the data variable is:
[{"name": "Bill", "age": 20},
{"name": "Mary", "age": 32},
{"name": "Jake", "age": 19}]
'''
with open("jsonfile.json", "w") as fileJson: # Opens Json file once again
  json.dump(data, fileJson) # Replaces the Json file using json.dump() method

Example 3: python to json

# a Python object (dict):
x = {
  "name": "John",
  "age": 30,
  "city": "New York"
}

# convert into JSON:
y = json.dumps(x)
