Coloring JSON output in python

In python, If I have a JSON object obj, then I can 

print json.dumps(obj, sort_keys=True, indent=4)

in order to get a pretty printout of the object. Is it possible to prettify the output even further: add some colors in particular? Something like the result of [1]

cat foo.json | jq '.'

I like using rich which has a dependency on pyments. But it covers all your console coloring needs, used in pip to show progress and also autoformats json: enter image description here

For python3 :

#!/usr/bin/python3
#coding: utf-8

from pygments import highlight, lexers, formatters
import json

d = {"test": [1, 2, 3, 4], "hello": "world"}

formatted_json = json.dumps(d, indent=4)
colorful_json = highlight(formatted_json, lexers.JsonLexer(), formatters.TerminalFormatter())
print(colorful_json)

The accepted answer doesn't seem to be working with more recent versions of Pygments and Python. So here's how you can do it in Pygments 2.7.2+:

import json
from pygments import highlight
from pygments.formatters.terminal256 import Terminal256Formatter
from pygments.lexers.web import JsonLexer

d = {"test": [1, 2, 3, 4], "hello": "world"}

# Generate JSON
raw_json = json.dumps(d, indent=4)

# Colorize it
colorful = highlight(
    raw_json,
    lexer=JsonLexer(),
    formatter=Terminal256Formatter(),
)

# Print to console
print(colorful)

You can use Pygments to color your JSON output. Based on what you have:

formatted_json = json.dumps(obj, sort_keys=True, indent=4)

from pygments import highlight, lexers, formatters
colorful_json = highlight(unicode(formatted_json, 'UTF-8'), lexers.JsonLexer(), formatters.TerminalFormatter())
print(colorful_json)

Output example:
