Yes, but interpreted by what?

I'm guessing that your shell is finding a "print" command on your PATH,
but that the "print" command can't find what it thinks to be a file.

This strongly corroborates the suspicion that your shell* is doing the
interpretation and not the Python interpreter.  No Python interpreter
would complain about import, and even if it did it would raise a Name
exception rather than using the "not found" message.

> Can't find file Hello world

This is the shell* compaining about the SECOND line of the script.

Aha!  So when the Python interpreter sees your script it does indeed
interpret it correctly.

You might want to look into

	http://www.toolwood.dk/freeware/PythonLauncher

or take advice about how otherwise to make Python scripts executable in the
Windows NT environment.  The "#!" hack is solely for U**x, sorry.
