Saving dict as JSON so that they are human readable

Question

When a dict is saved using json.dump, it is only a single-line. I want to make this a human-readable format such as this website does - https://jsonformatter.curiousconcept.com

How can I do this in python? I tried to capture pprint output, but it is an invalid string to store JSON in.

Specifically, is there an acceptable default way to do this in python directly?

You should utilize the indent and separators parameters in the json module. From the docs there:

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

why is your value ident 4 and not some other value? – Charlie Parker Oct 16 '20 at 20:03

@CharlieParker It's a common value (indent 4 spaces). You can set it to something else, if you want. – Ami Tavory Oct 16 '20 at 20:11
why do you need `separators=(',', ': ')`? – Charlie Parker Oct 16 '20 at 20:12
I ended up using: `json.dump(args_data, argsfile, indent=4)` – Charlie Parker Oct 16 '20 at 20:12
