No output from xlwings RunPython Macro

I am attempting to use a basic example of xlwings. I have the following VBA script:

Which is in the same directory as the python script VBAtester.py:

The VBA script runs and outputs the message box; but *'TEST VALUE'* does not show in cell A1, or elsewhere. I know the python script is being called as if I purposefully put errors in my python script VBA will callback these errors when I run the VBA script that calls the python script.

From the documentation, http://docs.xlwings.org/en/stable/quickstart.html, I do not see my error.

What is the error in my understanding or my approach?
