Summary Python JSON Handling Explained

Python JSON Handling – Complete
Study Notes
Introduction
JSON (JavaScript Object Notation) is a widely used data format for storing and exchanging
data between systems. In Python, JSON handling is an essential concept, especially when
working with APIs and web applications.

Python provides built-in support for JSON through the json module, making it easy to
convert data between JSON format and Python objects.

Understanding JSON handling is important for developers and data analysts because most
real-world data from APIs is received in JSON format.


Definition
JSON is a lightweight data interchange format that uses key–value pairs to represent data.

In Python, JSON data is usually converted into dictionaries for easy processing.

The json module provides functions such as loads(), dumps(), load(), and dump() to work
with JSON data.


JSON vs Python Dictionary
JSON and Python dictionaries are similar in structure but differ in syntax.

JSON uses double quotes for keys and values, while Python dictionaries can use single or
double quotes.

JSON data must follow strict formatting rules, while Python dictionaries are more flexible.


Converting JSON to Python
The json.loads() function is used to convert a JSON string into a Python dictionary.

This allows programmers to easily access and manipulate JSON data.

Example:

import json

data = '{"name":"Rahul","age":22}'
