[Tutor] Redirecting output

[Magnus Lyckå]

Rick, instead of redefining sys.stdout, which might confuse the
hell out of someone else (or yourself half a year later) who for
instance places a print statement somewhere for debugging, just
use "f = sys.stdout" in the default case, and use "print >> f, ..."
in all places where you want to be able to redirect output.
Actually, it would probably be clever to use a clearer variable
name than 'f'.

   print error_message

is the same as

   import sys
   error_stream = sys.stdout
   print >> error_stream, error_message

You were really very close here, weren't you? :)
