    >>> a = np.arange(15).reshape(3, 5)
    >>> a
    array([[ 0,  1,  2,  3,  4],
           [ 5,  6,  7,  8,  9],
           [10, 11, 12, 13, 14]])
    >>> a.shape
    (3, 5)
    >>> a.ndim
    2
    >>> a.dtype.name
    'int64'
    >>> a.itemsize
    8
    >>> a.size
    15
    >>> type(a)
    <type 'numpy.ndarray'>
    >>> b = np.array([6, 7, 8])
    >>> b
    array([6, 7, 8])
    >>> type(b)
    <type 'numpy.ndarray'>
