arcpy - Setting mask (halo) for labels in Python script?

I currently am writing a python script and using a lot of the arcpy mapping module functionality. I have been using the LabelClass of the arcpy mapping module to automate the display of labels with my ptyhon script.

Is there a way to set a mask (halo) for labels with ArcPy?

Answer

This is not possible via what is exposed to Python.

However, you can author a layer file and import it with the labels already defined for your workflow.
