通过从每个数组中选取 1 列来堆叠多个二维数组

Question

I have 3 numpy arrays of dimensions 20x308 each. I want to stack them so that i have the first column from 1st array, 1st column from 2nd array, 1st from 3rd and then 2nd from each and so on so that i will end up with 20x924 array. I have tried by looking at np.column_stack but that won't work. Thank You.

Answer 1

I have found a solution now, by using dstack and reshape.

    a = np.ones((2,3))
    b = np.zeros_like(a)
    d = [[1,3,5], [2,5,9]]
    c = np.dstack([a, b,d]).reshape(2,9)
