!cat ./configs/config.yml
config_reader = ConfigReader(name="myconfig")

default:
    config_int: 1

    config_list: [1, 2, 3]
    config_none: None
    config_dict:
        sub_config: "water"

A presets folder in the configs folder can be used to save and read presets settings.

!cat ./configs/presets/fire.yml

default:
    config_string: fire
    config_dict:
        sub_config: fire

# set the fire preset
pprint(config_reader.read(presets=("fire.yml",)), sort_dicts=False)

{'default': {'config_int': 1,
             'config_string': 'fire',
             'config_list': [1, 2, 3],
             'config_none': 'None',
             'config_dict': {'sub_config': 'fire'}}}

!cat ./configs/presets/water.yml || echo

default:
    config_string: water
    config_dict:
        sub_config: water

# set the water preset
pprint(config_reader.read(presets=("water.yml",)), sort_dicts=False)

{'default': {'config_int': 1,
             'config_string': 'water',
             'config_list': [1, 2, 3],
             'config_none': 'None',
             'config_dict': {'sub_config': 'water'}}}

User config and command line interface settings override presets settings.

user_config = {"myconfig": {"default": {"config_string": "water"}}}
# set the fire preset
pprint(
    config_reader.read(user_config=user_config, presets=("fire.yml",)), sort_dicts=False
)

{'default': {'config_int': 1,
             'config_string': 'water',
             'config_list': [1, 2, 3],
             'config_none': 'None',
             'config_dict': {'sub_config': 'fire'}}}
