[Paraview] Python shell, os.environ

[Utkarsh Ayachit]

Randy,

No, `os` hasn't been hijacked by PV.  Here's what I get on Linux.

./bin/pvpython
Python 3.5.2 (default, Nov 23 2017, 16:37:01)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.environ["FOO"]
'12'


I suspect it's something to do with App bundles on macOS and what
environment variables they see based on how you launch them. I can't
remember that of the top of my head, but that's where I'd start
looking.
