List.Combine node to design script or python

Hi , I have to optimize some sripts using Python or design script. No zero touch nodes.
So, i can´t " node to code" the list. combine node. or Idon´t know how to create a python code for that.
Please help
(Revit 2018.3 and Dynamo 1.3.2 is used)

The Combine node is kinda redundant here. Why can’t you just use FilterByBoolMask?
