how to read json file

[snippsat]

Look like you have been given this a task as homework.
With some Java code as a start and that you should write it Python.
So is this homework?

Just to give some hint on a start.

Step 1: You have to read the file, If any Error, please correct.

import json

with open("data.json", "r") as read_file:
    data = json.load(read_file)

This read the json file,look into try:except for catching error.

What the json file return is Python dictionary,here is it normal to have a mix of dict and list as your data show.
Can use direct access or a get method as the Java code has.

>>> data
{'age': 35,
 'children': [{'age': 6, 'firstName': 'Alice'}, {'age': 8, 'firstName': 'Bob'}],
 'firstName': 'Jane',
 'hobbies': ['running', 'sky diving', 'singing'],
 'lastName': 'Doe'}

>>> # Direct access
>>> data['children'][0]['firstName']
'Alice'
>>> 
>>> # Using get here can also do error check
>>> data['children'][0].get('firstName', 'Not in Record')
'Alice'
>>> data['children'][0].get('firstName9', 'Not in Record')
'Not in Record'
