False is just a constant. 0, (), '', [], and False are all constants that happen to evaluate to a false value in a Boolean context, but they are not all the same. As a general rule, I've found code like "if x == False" to be a bad idea in ANY language. -- Tim Roberts, [EMAIL PROTECTED] Providenza & Boekelheide, Inc. -- http://mail.python.org/mailman/listinfo/python-list
