This is probably about as close as you're going to get:

  import sys
  pring open(sys.argv[0],'r').read()

And that isn't 100% reliable.

It isn't.  At least none of the implimentations I know of have
the script's source code in memory.  The PVM or JVM bytecodes
to which the program has been compiled are in memory somewhere,
and there _may_ be some trick you can use to get at those.

I don't believe so.
