[Numpy-discussion] test if two arrays share the same data

Hi, How can it be done? id() doesn't do it: In [238]: a= np.arange(5) In [239]: id(a) == id(a[:]) Out[239]: False Any ideas? Ernest ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
