so? that's the original Python way of doing things, and is both very readable and surprisingly efficient: $ timeit -s "d = vars()" "for k in d: v = d[k]" 1000000 loops, best of 3: 0.472 usec per loop $ timeit -s "d = vars()" "for k, v in d.iteritems(): pass" 1000000 loops, best of 3: 0.663 usec per loop </F> -- http://mail.python.org/mailman/listinfo/python-list
