No, they don't make any semantic difference; they work just like any other identifier. It's just that, by convention, single underscores indicate that we don't care what values these names are bound to. So in the example above, Heiko indicates that we don't care about what you would normally call 'root' and 'dirs'. HTH, STeVe -- http://mail.python.org/mailman/listinfo/python-list
