You only need to change the list() for empty list

Load the Python Standard and DesignScript Libraries

import sys
import clr
clr.AddReference(‘ProtoGeometry’)
clr.AddReference(“RevitServices”)
from Autodesk.DesignScript.Geometry import *
import RevitServices
from RevitServices.Persistence import DocumentManager

doc = DocumentManager.Instance.CurrentDBDocument

The inputs to this node will be stored as a list in the IN variables.

faces = UnwrapElement(IN[0])
elementlist =
for face in faces:
ref = face.Tags.LookupTag(“RevitFaceReference”)
elem = doc.GetElement(ref)
elementlist.append(elem)

Assign your output to the OUT variable.

OUT = elementlist

please import clr and use list with elementlist= [ ].Some thing like that:

import clr
clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager

doc = DocumentManager.Instance.CurrentDBDocument
faces = UnwrapElement(IN[0])
elementlist = []
for face in faces:
	try:
		ref = face.Tags.LookupTag("RevitFaceReference")
		elem = doc.GetElement(ref)
		elementlist.append(elem)
	except:
		elementlist.append()
OUT = elementlist
