Python yaml dump confuse

Question

Let's say I have a json file like below, call it `src.json`. ``` { "main": { "contenttype": "Document" }, "dublin": { "title": "ダウンロード", "description": "", "creators": [ "池田大作" ], "created": "2012-04-23 10:09:34.642940" } } ``` I wanna dump the `dublin` contents to `dst.yaml` using `yaml` in `python`. Here is my code: ``` import json import yaml with open('src.json') as f: data = json.load(f) dump = {'title': data.get('dublin', {}).get('title', ''), 'description': data.get('dublin', {}).get('description', ''), 'creator': data.get('dublin', {}).get('creators',[''])[0], 'created': data.get('dublin', {}).get('created', '') } with open('dst.yaml', 'w') as stream: yaml.safe_dump(dump, stream, allow_unicode=True ) ``` However, I am not satisfied with the result: ``` {created: '2010-03-26 09:26:44.002029', creator: 池田大作, description: ' ', title: ダウンロード} ``` The satisfied one should be : ``` created: 2010-03-26 09:26:44.002029 creator: 池田大作 description: '' title: ダウンロード ``` Then, my questions…

Accepted Answer

- Because it has a space in it.

- Set `default_flow_style=False` in your call to `yaml.dump()`.

Also, you don't need to do all of that reconstruction; you could just dump the existing dublin dict directly:

```
import json
import yaml

with open('src.json') as f:
    data = json.load(f)

with open('dst.yaml', 'w') as stream:
    yaml.safe_dump(data.get('dublin', {}), stream, allow_unicode=True,
                   default_flow_style=False)
```
