Setting up a try...except block is very fast, but actually responding to an exception is very slow. You _might_ find that it is quicker to evaluate both expressions than it is to catch the exception. Better still is to find another way of avoiding both the exception and the symmetrical calls. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
