How to add some empty line when using `json.dumps` on Python 3?

Question

For example, I have a dictionary like this:

d = {'Name': 'Jone', 'Job': 'Boss', 'From': 'England', (and many many more...)}

As you can see, this dictionary is very very long. so I can display it in my code like this:

 a = {'Name': 'Jone',
      'Job': 'Boss',
      'From': 'England',
      (and many many more...)}

But when I using json.dumps to save this dictionary in a file, it will display as one line. So it's hard to check and edit.

So how can I save a dictionary use json in more line, and load that? use str.split when load and dump?

No problem! json.dumps has some built in options to help out.

Try doing it like this...

string = json.dumps(d, indent=4, sort_keys=True)

And write your new string to the file. :)

The API is that you specify the indent you would like for each line:

import json

print(json.dumps(dict(a=1, b=2), indent='    '))

{
    "a": 1,
    "b": 2
}

All good with me :-) So long as you got the answer you needed. I actually ran into the same thing yesterday myself.
