How to fill default parameters in yaml file using python -

-

i have yaml file content:

       image_name: ubuntu        components:                  image_name: ubuntu                  image_flavors: [medium, large]                  image_ip : 192.168.12.134                  imageuser : ubuntu                  image_pass : ubuntu                  image_config: /home/ubuntu/                  image_net_type: vlan                   image_switch_type: ovs

i have implemented script load yaml file , o/p have got in dict format.

       open("test.yaml", "r") input:         try:             = yaml.safe_load(input)             print "parsing yaml file completed"             print         except yaml.yamlerror error:             print(error)

my dict format below:

{'image_name': 'ubuntu', 'components': {'image_ip': '192.168.12.134',   'image_pass': 'ubuntu', 'image_switch_type': 'ovs', 'imageuser': 'ubuntu',  'image_name': 'ubuntu', 'image_flavors': ['medium', 'large'],   'image_net_type': 'vlan', 'image_config': '/home/ubuntu/'}}

how can fill default parameters if key has no values?

hmm, mean this:

default_values = {     'image_name': 'some',     'components': {          'image_ip': '192.168.1.1',          'image_pass': 'default_password',          'image_switch_type': 'ovs',          'imageuser': 'default_user',          'image_name': 'default_name',          'image_flavors': ['medium', 'large'],          'image_net_type': 'vlan',          'image_config': '/default/home/'      } }  def setdefault_recursively(tgt, default = default_values):     k in default:         if isinstance(default[k], dict): # if current item dict,             # expand recursively             setdefault_recursively(tgt.setdefault(k, {}), default[k])         else:             # ... otherwise set default value if it's not set before             tgt.setdefault(k, default[k])  dic = { 'image_name': 'ubuntu', 'components': { 'image_name': 'ubuntu' }  setdefault_recursively(dic)

?

this should fill dic read yaml file default values, recursively:

{'components': {'image_config': '/default/home/',             'image_flavors': ['medium', 'large'],             'image_ip': '192.168.1.1',             'image_name': 'ubuntu',             'image_net_type': 'vlan',             'image_pass': 'default_password',             'image_switch_type': 'ovs',             'imageuser': 'default_user'},  'image_name': 'ubuntu'}

that is, settings within structure weren't explicitly set yaml file, have received default values default_values, uhmm, recursively.
