Hi Ruben, > In both cases, as the print > statement shows, offspr is already created.
>>> offspr[...] = r + a[:, None] means "fill the existing object pointed by offspr with r + a[:, None]" while >>> offspr = r + a[:,None] means "create a new array and assign it to the variable offspr (after decref-ing the object previously pointed by offspr)" Best, Luca _______________________________________________ NumPy-Discussion mailing list [email protected] http://mail.scipy.org/mailman/listinfo/numpy-discussion
