code: def get_arguments(self, **include):
          
          d = dict(self._kwargs)
  
          for k in include:
              if not include[k] and k in d:
                  d.pop(k)
          return d
docs: return a shallow copy of self._kwargs
          passing {key}=False will pop the {key} from the dict
          e.g. get_arguments(inputs=False) returns all keywords except inputs
