Outputting yaml in dict format

Question

I have a list of dict that looks like this

data = {'items': [{'id': '1', 'desc': 'Item 1', 'cat': 'cat1'}], 'categories': [{ 'id': 'cat1', 'desc': 'category number 1' }]}

I want to dump this in the following yaml format

---
items:
    - { id: 'it1', desc: 'item number 1', cat: 'cat1' }
categories:
    - { id: 'cat1', desc: 'category number 1' }

using yaml.dump(data) outputs a yaml in the following format

categories:
- desc: category number 1
  id: cat1
items:
- cat: cat1
  desc: Item 1
  id: '1'

What do I need to add to change this? I have tried setting the default_flow_style=False with no difference.

Another solution is by using `ruamel.yaml` which is answered in another thread: https://stackoverflow.com/a/36760452/1279157 — Ronie Martinez, Mar 13 '20 at 02:59
yaml file just like json file, where you can get keys and values like resemblance of json file — Saisiva A, Mar 13 '20 at 06:38

In PyYAML, the option default_flow_style has three different values:

We changed the default from None to False in version 5.1 because many people complained about it. So you need default_flow_style=None.
