What are you trying to do ?

view = UnwrapElement(IN[0])
v=view.Name

OUT = v

OR :

import clr
clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager
doc = DocumentManager.Instance.CurrentDBDocument

clr.AddReference('RevitNodes')
import Revit
clr.ImportExtensions(Revit.Elements)

view = doc.ActiveView.ToDSType(True)
v=view.Name

OUT = v
