Pretty Printing JSON in Python

Pretty printing a JSON file enhances its readability by indenting and formatting its content for human readers. In Python, this can be achieved using the json.dump() or json.dumps() functions.

Using json.dump() and json.loads()

To pretty print a string containing JSON data:

import json

# JSON string
your_json = '["foo", {"bar": ["baz", null, 1.0, 2]}]'

# Parse the JSON string
parsed = json.loads(your_json)

# Pretty print the JSON object with 4 spaces of indentation
print(json.dumps(parsed, indent=4))

Using json.load() and json.dumps() with a File:

# Open a file containing JSON data
with open('filename.txt', 'r') as handle:
    # Parse the JSON file
    parsed = json.load(handle)

# Pretty print the JSON object with 2 spaces of indentation
print(json.dumps(parsed, indent=2))
