Wouldn't your version get a NameError on the "if answer == 'yes'" line in the case of a ZeroDivisionError or ValueError? To the original poster.... what environment are you running this in? When I put your program in notepad and run it from the windows command prompt it works. But when I paste it into eclipse and run it eclipse's console, it doesn't work because answer seems to have a stray '\r' carriage return (CR) and therefore the comparison to 'no' fails. -- http://mail.python.org/mailman/listinfo/python-list
