How to Parse Data From JSON into Python?

The json module in Python provides an easy way to convert JSON data into Python objects. It enables the parsing of JSON strings or files into Python's data structures like dictionaries. This is helpful when you need to process JSON data, which is commonly used in APIs, web applications, and configuration files.

Python JSON to Dictionary

json.loads() function parses a JSON string into a Python dictionary.

import json geek = '{"Name": "nightfury1", "Languages": ["Python", "C++", "PHP"]}' geek_dict = json.loads(geek) # Displaying dictionary print("Dictionary after parsing:", geek_dict) print("\nValues in Languages:", geek_dict['Languages']) 

Output:

Dictionary after parsing:  {'Name': 'nightfury1', 'Languages': ['Python', 'C++', 'PHP']}

Values in Languages:  ['Python', 'C++', 'PHP']

Python JSON to Ordered Dictionary

To parse JSON objects into an ordered dictionary, use the json.loads() function with object_pairs_hook=OrderedDict from the collections module.

import json from collections import OrderedDict data = json.loads('{"GeeksforGeeks":1, "Gulshan": 2, "nightfury_1": 3, "Geek": 4}', object_pairs_hook=OrderedDict) print("Ordered Dictionary: ", data) 

Output:

Ordered Dictionary:  OrderedDict([('GeeksforGeeks', 1), ('Gulshan', 2), ('nightfury_1', 3), ('Geek', 4)])

Parse using JSON file

json.load() method parses a JSON file into a Python dictionary. This is particularly useful when the data is stored in a .json file.

import json with open('data.json') as f: data = json.load(f) # printing data from json file print(data) 

Output:

{'Name': 'nightfury1', 'Language': ['Python', 'C++', 'PHP']}
