Manually step through what this line should do. Follow the exact same rules Python will follow in evaluating this expression. http://docs.python.org/2/reference/expressions.html#operator-precedence http://docs.python.org/3/reference/expressions.html#operator-precedence As you'll see from footnote 8 or 5 (depending on which version of the docs), your percent operator is the same one listed in the table as a division operator. Now. Go through that expression, step by step. Walk through everything the Python interpreter does. Figure out exactly what happens first, second, third. Figure out when your percent operator gets handled. Then you'll know what's wrong with that line of code. You'll also gain a very useful understanding of Python, and more generally of the way most high level languages parse expressions. ChrisA -- http://mail.python.org/mailman/listinfo/python-list
