print(hou.hipFile.path())
Get the version numbers in the filename
hou.hscript('echo -n `opdigits($HIPNAME)`')
What platform is Houdini running on?

List all the environment variables
import os
for e in os.environ:

Reload a module, useful if you make some changes to the module.
import importlib importlib.reload(module)
