Get Revit Elements by UniqueID (GUID) from Dynamo

dynamo_get-revit-elements-by-guid.py

import clr
clr.AddReference("RevitAPI")
import Autodesk
from Autodesk.Revit.DB import ElementId
clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager
clr.AddReference("System")
from System.Collections.Generic import List

doc = DocumentManager.Instance.CurrentDBDocument

guids = IN[0]

if not isinstance(guids, list):
	guids = [guids]
	
elems = []

for g in guids:
	hexid = g[37:]
	id = int(hexid, 16)
	elem = doc.GetElement(ElementId(id));
	elems.append(elem)


OUT = elems

Change line 21 to be:

hexid = str(g[37:])

Worked for me in Revit 2022, Dynamo 2.12.1
