It works if you pre-allocate the array: In [18]: x = [(1,2),(3,4)] In [19]: z = N.empty(len(x),dtype='O') In [20]: z[:] = x In [21]: z Out[21]: array([(1, 2), (3, 4)], dtype=object) Regards Stéfan _______________________________________________ Numpy-discussion mailing list Numpy-discussion@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/numpy-discussion
