Hi @doc-xie - `xrange` was available in older Slicer versions that used Python2, but it’s not in Python3, so it should be `range` instead. There’s some background on the transition here: [Updating slicer to work with python 3](https://discourse.slicer.org/t/updating-slicer-to-work-with-python-3/4662)
