Piece of cake: the key part of this recipe is
    def whereami(): return sys.modules[__name__].__file__
then you can os.path.abspath this filename string as you wish.

Here's a more complete example

#!/usr/bin/env python

import sys, os

def whereami(): return os.path.abspath(sys.modules[__name__].__file__)

if __name__ == '__main__': print whereami()

Put this anywhere on your $PATH, chmod +x it, and try out what you see
by executing it as the main script from various locations... should work
pretty reliably.

Sure, that shouldn't be impossible.
