问题 I came across this difficulty accessing multiple fields (columns) input: a = np.array([(1.0, 2,1),(3.0, 4,2),(9, 3,6)], dtype=[('x', float), ('y', float), ('z', float)]) a=np.reshape(a,(a.shape[0],-1)) a output: array([[(1.0, 2.0, 1.0)], [(3.0, 4.0, 2.0)], [(9.0, 3.0, 6.0)]], dtype=[('x', '<f8'), ('y', '<f8'), ('z', '<f8')]) if i want to access the first column i can do: in: a[:]['x'] out: array([[ 1.], [ 3.], [ 9.]]) but what is the right syntax if i want to access (for example) first an 3rd
