I loved the use of __rdiv__ :) I would have proposed the more straightforward: def u(v): return [x/sum(x**2 for x in v)**0.5 for x in v] or, in order to avoid computing the norm for each element: def u(v): return (lambda norm: [x/norm for x in v])(sum(x**2 for x in v) **0.5) -- Roberto Bonvallet -- http://mail.python.org/mailman/listinfo/python-list
