Because your statement is incorrect. Everything has a boolean value in Python. 0, None, False, '' (empty string), [] (empty list), () (empty tuple), and {} (empty dictionary) all have a False value. Everything else has a True value. Python didn't even have a boolean type (True and False) until rather recently (2.2?). This is a very handy feature, and it's one of the things I love about Python. >so obv while var means while not empty or why not zero but it isnt >something youd guess unless youd beeen shown it. It's clearly stated in the documentation. I don't know how you concluded that True and False were the only boolean values. -- Tim Roberts, [EMAIL PROTECTED] Providenza & Boekelheide, Inc. -- http://mail.python.org/mailman/listinfo/python-list
