I doubt if there's any particular way to do it consistently.  In 
principle one could write a cute module which would be able to check
the "signature" of the environment to figure it all out.  Check if 
certain modules are in __builtins__ to see if you are running inside
an application that uses Python for scripting, check for sys.argv[0]
to learn whether you were launched in a way that suggests running as
a script with python.exe, etc.

It's probably not a great idea to write anything which depends on this
however, and it sounds like more time than it's worth.
