You don't need to build the format string dynamically to get control of the maximum width. A neat trick is that if you use '*' for the format width, the width will be read from the parameter list: In [30]: '%*.3f' % (5, 1.2) Out[30]: '1.200' In [31]: '%*.3f' % (10, 1.2) Out[31]: ' 1.200' Kent _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
