: import traceback, sys

: for stuff in things_to_do():
:     try:
:         do(stuff)
:         print stuff, "ok"
:     except:
:         print stuff, "FAILED"
:         traceback.print_exc(file=sys.stdout)

Or if you don't mind all stderr going to stdout, just:
  import sys
  sys.stderr = sys.stdout

The traceback module routines all use the current value of "sys.stderr"
at the time of the exception.
