A bit fragile, since it uses eval: lst = eval(repr([[[0]*3]*3]*10)) but in this particular case, eval won't leak harmful code (as far as I can see) since all it process is literals, not user-inputted data. The alternative is this: lst = [[[0 for _ in range(3)] for _ in range(3)] for _ in range(10)] _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
