YAML Formatting

[raunakdoesdev]

YAML lists should be formatted compactly as [1, 2, 3, 4] rather than

- 1
- 2
- 3
- 4

I think this issue can be managed by the default_flow_style kwarg. Should I change the default kwarg to be "default_flow_style=True"? @zhijian-liu

Thanks! I actually tried to tweak this before; however, it does not work as expected.

Here is a sample testing code:

import yaml
import tempfile

configs = {
    'a': 1,
    'b': [1, 2, 3, 4],
    'c': {
        'd': 1
    }
}

for default_flow_style in [True, False, None]:
    print(yaml.dump(configs, default_flow_style=default_flow_style))

The output of default_flow_style=True is

{a: 1, b: [1, 2, 3, 4], c: {d: 1}}

The output of default_flow_style=False is

a: 1
b:
- 1
- 2
- 3
- 4
c:
  d: 1

The output of default_flow_style=None is

a: 1
b: [1, 2, 3, 4]
c: {d: 1}

I somehow expect a mixture of the last two:

a: 1
b: [1, 2, 3, 4]
c:
  d: 1

Would love to know what you think. Thanks!
