How to prettyprint (human readably print) a Python dict in json format (double quotes)?

Question

This is a follow-up question to this one. I need to both prettyprint a python dict (so I can visually inspect/modify it), and I need to have the output in json format (with the double quotes).

pprint module prettyprints the dict but uses single quotes (not json!). That's the topic of the linked other question/answer.

json.dumps will use the double quotes, but prints it in a big line (not human readable!)

How can we achieve both?

See the docs:

import json

print(json.dumps(
    {'4': 5, '6': 7},
    sort_keys=True,
    indent=4,
    separators=(',', ': ')
))

While it would convert the `None` object to `null` which raise null was not a object exception – Ryan Chou Oct 30 '17 at 02:38

You might want to add `ensure_ascii=False`, otherwise unicode characters will look like `\u0435`. – Boris Verkhovskiy Dec 06 '19 at 19:59
@RyanChou you can do `null = None` before importing/copy pasting the result to avoid the exception. – Boris Verkhovskiy Dec 06 '19 at 20:04
In python3.4+, no need to specify separators as `(',', ': ')` as that is the default (even if indent is not `None`) – Osama Dar Jan 20 '23 at 16:09
