Here is the code -

import clr
clr.AddReference(‘ProtoGeometry’)
from Autodesk.DesignScript.Geometry import *

Import DocumentManager and TransactionManager

clr.AddReference(“RevitServices”)
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

Import RevitAPI

clr.AddReference(“RevitAPI”)
import Autodesk
from Autodesk.Revit.DB import *

doc = DocumentManager.Instance.CurrentDBDocument
uiapp = DocumentManager.Instance.CurrentUIApplication
app = uiapp.Application

from System.Collections.Generic import *

#The inputs to this node will be stored as a list in the IN variable.
dataEnteringNode = IN

#unwrap all elements to use with API
elements = []
for i in IN[0]:
elements.append(UnwrapElement(i))

idsToDelete = ListAutodesk.Revit.DB.ElementId
for i in elements:
idsToDelete.Add(i.Id)

“Start” the transaction

TransactionManager.Instance.EnsureInTransaction(doc)

doc.Delete(idsToDelete)

“End” the transaction

TransactionManager.Instance.TransactionTaskDone()

message = “You have successfully deleted n " + str(idsToDelete.Count) + " elements from Revit model.”

OUT = ‘n’.join(’{:^35}’.format(s) for s in message.split(‘n’))
