3.12.1 Traceback Example
This simple example implements a basic read-eval-print loop, similar to (but less useful than) the standard Python interactive interpreter loop. For a more complete implementation of the interpreter loop, refer to the code module.
import sys, 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) print '-'*60 envdir = {} while 1: run_user_code(envdir)
