eval?

<ducking, running for cover>

// m

p.s.  but seriously, do you have a more realistic example?  Surely your
motivation is more than merely to write obfuscated code.  If not, you could

  import os
  guy = os.name
  print guy

Or are you looking for string interpolation?  search the archives of
