Working with Python – JSON

Introduction
JSON (Java Script Object Notation) is very popular nowadays for transmitting data. Here in this Blog Post we are going discuss about it.

Hope it will be interesting.

 

Importing JSON module

Before working with JSON, we have to import the JSON module in Python.

import json

Parsing JSON in Python

We can Parse JSON in multiple ways in Python mentioned bellow.

Parsing JSON to Dictionary

We can Parse a JSON using json.loads() methods, which returns a Dictionary.

 

Example:

Import  json

person = '{"name": "Mayuree", "languages": ["English", "Bengali"]}'
person_dict = json.loads(person)
print( person_dict)
print(person_dict['languages'])

Output:

{'name': 'Mayuree', 'languages': ['English', 'Bengali']}
['English', 'Bengali']

Here, person is a JSON string and person_dic is adictionary.

 

 

Read the JSON File

 

Now, it’s time to read a JSON file by python. For example, we are using same JSON string as a file.

 

Example:

import  json
with open('person.json') as f:
data = json.load(f)
print(data)

 

Output:

{'name': 'Mayuree', 'languages': ['English', 'Bengali']}

 

In the above example, the OPEN is used to read the JSON file and JSON.LOAD() function is used to parse the JSON file into Dictionary.

 

Converting Dictionary to JSON string

 

We can convert Dictionary to a JSON string using json.dumps() method.

 

Example:

Import  json
person_dict = {'name': 'Mayuree',
'age': 22,
'children': 2}
person_json = json.dumps(person_dict)
print(person_json)

Output:

{"name": "Mayuree", "age": 22, "children": 2}
