Python One‑Liner: Pretty‑Print JSON String for Readability! 🔄📑 #PythonTips #CodingShorts

Pretty‑printing JSON transforms a compact, hard‑to‑read JSON string into a human‑friendly format by adding newlines and indentation

This is invaluable when working with API responses, configuration files, or log data in Python

Long Way Explanation:

Output: Print the resulting multi‑line string for easy inspection

One‑Liner Explanation:

Combine parsing and formatting into a single expression:

This leverages the JSON module’s built‑in methods for concise, readable code

By relying on Python’s standard library, this approach avoids external dependencies and handles complex JSON structures—including nested lists and objects—robustly

Use this one‑liner in Jupyter notebooks or shell scripts to streamline debugging, logging, and data exploration workflows

Codes:

Long Way: Load and dump with json module

import json
s = '{"name":"Alice","age":30,"languages":["Python","JavaScript"],"active":true}'
# Parse JSON string into Python object
# Serialize with indentation and sorted keys
print(pretty)
# Output the formatted JSON

One‑Liner: Chain loads and dumps

# Output:
# {
# "active": true,
# "age": 30,
# "languages": [
# "Python",
# "JavaScript"
# ],
# "name": "Alice"
# }
