I've add the source and a python notebook to get a config from discovery using the python sdk (version 0.23 has discovery)

discovery_config_fetch.py

import watson_developer_cloud

DISCOVERY_USERNAME='CHANGE_ME'
DISCOVERY_PASSWORD='CHANGE_ME'
ENVIRONMENT_NAME='CHANGE_ME'
CONFIGURATION_NAME='CHANGE_ME'

discovery = watson_developer_cloud.DiscoveryV1(
    '2016-12-15',
    username=DISCOVERY_USERNAME,
    password=DISCOVERY_PASSWORD)


environments = discovery.get_environments()

target_environment = [x for x in environments['environments'] if x['name'] == ENVIRONMENT_NAME]
target_environment_id = target_environments[0]['environment_id']

configs = discovery.list_configurations(environment_id=target_environment_id)
target_config = [x for x in configs['configurations'] if x['name'] == CONFIGURATION_NAME]
target_config_id = target_config[0]['configuration_id']

config_data = discovery.get_configuration(environment_id=target_environment_id,
                                          configuration_id=target_config_id)
print(config_data)
