python-jsonparser

This package will help you to reduce your stress :) while parsing json in python. Follow the steps below for using python-jsonparser

1. Install the package from pypi

pip install python-jsonparser

2. Now let's assume we have a json object as below.

dummy = {
    "name": {
        "first_name": "ABC",
        "last_name": "EFG"
    },
    "details": {
        "phone":["xxxxxxxxx", "00xxxxxxx", "0000000000"]
    }
}

3. Now assume we want first_name, last_name and only first phone number from the list. For this create a class TestClass as below and inherit JSONParser from :

from json_parser import JSONParser

class TestClass(JSONParser):
    first_name = 'name/first_name'
    last_name = 'name/last_name'
    phone = 'details/$1'

4. Create instance of your class and pass the json object.

test_obj = TestClass(dummy)

5. Now call the validate method from the object created.

output = test_obj.validate()

6. You will have following as the output:

{
    'first_name': 'ABC',
    'last_name': 'EFG',
    'phone': '00xxxxxxx'
}

7. For getting the range of elements from the list you can use $x:$y

from json_parser import JSONParser

class TestClass(JSONParser):
    first_name = 'name/first_name'
    last_name = 'name/last_name'
    phone = 'details/$1:$3' # This will give you 2 values from the list

# Output:
# {
#     'first_name': 'ABC',
#     'last_name': 'EFG',
#     'phone': ['00xxxxxxx', '0000000000']
# }

8. This was all about single object. What if you have json list of objects. In that case set many=True while creating the instance of your class. For example:

test_obj = TestClass(dummy, many=True)
