Numpy Play with Rows and Columns of a Matix

[quest]

Hello
I created my code as I want and now I just want to change my matrix.
As a result of my code, I have this matrix:



And here I want to write each column as a rows and after that I want to add them together. As a result I should see this image:



Here is my code(I just add the related part):

………….. ##I didn't paste here because we have just definition of list
for triplet in itertools.product([0, 1], repeat=6):
    arr = np.array([])
    for i in range(8):
        for l in range(8):
            if l[l] == n[i]:
                arr = np.append(arr,[1])
                
            else:
                arr = np.append(arr,[0])
                
    print(arr)

How can I change my matrix from first image to second image?
