How to Load JSON into a Variable in Python

JSON, which stands for JavaScript Object Notation, is a popular data format used for transmitting data between a server and a client. In Python, loading JSON data into a variable is a straightforward task thanks to the built-in json module.

Understanding JSON and Python's json Module

JSON is a text format that is completely language-independent but uses conventions that are familiar to programmers of the C family of languages. This includes Python, making it easy to parse and generate JSON data.

Python's json module provides an easy method for encoding and decoding JSON. The json module exposes several functions to load and parse JSON data.

Importing the json Module

First, you'll need to import the json module. This is done using the following code:

Handling Nested JSON

JSON data can often be nested, meaning one JSON object or array can contain another JSON object or array. The json module handles this gracefully, converting nested JSON structures into nested Python dictionaries and lists.

Here, data will be a nested Python dictionary that mirrors the structure of the JSON data.

Error Handling

When working with JSON data, it's essential to handle potential errors, such as malformed JSON or file not found errors.
