	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
