在Python 3上使用json.dumps时，如何添加一些空行？

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?

Answer 1

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
}

Answer 2

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. :)
