Using the parsed values

The parsed values by params.parse() or params.values() are attached to a namespace. Yes, argparse's Namespace. So this will be true:

from argparse import Namespace
from params import Params
params.add_param('i', default=1)
values = params.values()

isinstance(values, Namespace)

However, it is not exactly the same, meaning this is NOT true:

from argparse import Namespace as APNamespace
from params import PMNamespace
PMNamespace is APNamespace

But PMNamespace is a subclass of APNamespace, with following functionalities being added:

• Subscription:

  ns = PMNamespace()
  ns['a'] = 1
  ns['a'] == 1
  

• Length:

  len(ns['a']) == 1
  

• Key existence detection:

  'a' in ns is True
  

You can turn a namespace into a dictionary by vars(ns). However, if you want to turned all the namespaces inside into dictionaries, you may need to do it recursively.
