That is an old trick.  I believe it can be done in almost any
language.  Here is one solution for Python:

v = 'v = %s ; print v[:3], `v`, v[7:]' ; print v[:3], `v`, v[7:]

The interesting part about these types of programs is that you
can add an arbitrary amount of code once it is working.  This is
similar to how computer viruses copy themselves.
