If you really need to append elements, you probably want to use a list and then convert to an array afterwards. But if you know your array size, you can preallocate memory and then fill it. E.g., >>> ST = np.empty((10,),dtype=np.float32) >>> for i in range(10): ST[i]=i hth, Alan Isaac PS Some users suggest it is better practices to use `zeros` rather than `empty`. Note that `zeros` has the same property that surprised you. >>> np.zeros((),dtype=np.float32) array(0.0, dtype=float32) >>> np.append(np.zeros((),dtype=np.float32),99) array([ 0., 99.]) _______________________________________________ Numpy-discussion mailing list [email protected] http://projects.scipy.org/mailman/listinfo/numpy-discussion
