I looked up the jython code to print out the trace when an exception
occurs

This exception .py will not evec "compile"

Any suggestions would be helpful.
Thanks

copy from example:
http://www.python.org/doc/2.1/lib/traceback-example.html

import sys, traceback        # not acceptible

     def run_user_code(envdir):
         source = raw_input(">>> ")
         try:
             exec source in envdir
         except:
             print "Exception in user code:"
             print '-'*60
             traceback.print_exc(file=sys.stdout)
             print '-'*60

     envdir = {}
     while 1:
         run_user_code(envdir)

also tried:

from sys import traceback
def run_user_code(envdir):
 source = raw_input(">>> ")
 try:
  exec source in envdir
 except:
  print "Exception in user code:"
  print '-'*60
  traceback.print_exc(file=sys.stdout)    # not found
  print '-'*60

envdir = {}
while 1:
   run_user_code(envdir)
