While you are making the transition you could write from perl_idioms import open_or_die f = open_or_die("does-not-exist") with the perl_idioms module looking like import sys def open_or_die(*args): try: return open(*args) except IOError, e: sys.exit(e) Peter -- http://mail.python.org/mailman/listinfo/python-list
