I looked into PC/getpathp.c. The value of PythonPath shown above is
only a fallback for when Python is embedded. Otherwise the interpreter
can determine sys.prefix from the exe path, and substitute it for the
dots in the following hard-coded path:
.\DLLs;.\lib;.\lib\plat-win;.\lib\lib-tk

Ah, useful. A lot more than is on windows path and PYTHONPATH
obviously gets snuck in there. Sure enough, I queried sys.path and
there's a Lot more in there. But even that wasn't everything since I
saw RLPy and vtk had also set up their own system variables when I
checked the environment. But those are special variables. From now on
if I'm not sure something is on the path I can just query sys.path and
see if it's there. Good to know.
If I dump a package (not sure how to do that beyond just deleting it,
but I've tried some bad ones, so I'd like to) how do I remove it from
sys.path, or do I need to? I know the windows path and the registry
have a bad habit of accumulating stuff that is no longer there, and
just keeping it. Programs add to the windows path, but when you
uninstall them, don't delete from the path, and it grows and grows.
On Windows Vista Control Panel->System->Advanced System Settings->System
Properties->Advanced->Environment Variables. The path is displayed as a
user setting and a system setting, edit either at your own risk.
Programs are available to clear unused settings from the registry. I
use them quite happily but if you're unsure of what you're doing I'd
just leave things alone, you'll probably sleep better for it :)
