Convert lists into higher dimension so that elements can be reached by following-CodePudding

I have a matrix that I want to convert to 3D so that I can be able to print the element of list[i][j][k]

a = [[[0, 1, 2, 3, 4, 5], [1, 2, 3, 4, 5, 6], [2, 3, 2, 3, 4,5], [3, 2, 3, 4, 3, 4], [4, 3, 4, 5, 4, 3], [5, 4, 5, 6, 5, 4]]]

print(a[5][5][0]) # I want to be able to print in 3D`

I get right output if I do a[5][5] but wrong when I add the [0]. Is there anyway of converting my matrix such that this will be solved?

I tried to just wrap the list up with brackets [list], but it did not work. I also did: b = [[i] for i in a]

which gave me [[[0,1,2,3,4,5]],[[1,2,3,4,5,6]],... and it still did not work!

NOTE: I want the i to be the row, j to be the column and k to be 0 or 1, so k = 0 (in which case the value is the row index of the cell is pointing to), or the k = 1 (the value is the column index).

Tried to reproduce your issue. To me, it works if you use the right index. Here, it perfectly works if you do for instance

print(a[0][0][5]) # I want to be able to print in 3D`

for list a = [[[0, 1, 2, 3, 4, 5], [1, 2, 3, 4, 5, 6], [2, 3, 2, 3, 4,5], [3, 2, 3, 4, 3, 4], [4, 3, 4, 5, 4, 3], [5, 4, 5, 6, 5, 4]]] you have just a[0][n][n]. You can try a[0][5][5] You have index like below:

a = [
        #0 element i
        [
            #0 element j
            [0, 1, 2, 3, 4, 5], 
            #1 element j
            [1, 2, 3, 4, 5, 6], 
            #2 element j
            [2, 3, 2, 3, 4,5], 
            #3 element j
            [3, 2, 3, 4, 3, 4], 
            #4 element j
            [4, 3, 4, 5, 4, 3], 
            #5 element j
            [5, 4, 5, 6, 5, 4]
        ]
    ]

print(a[0][5][5]) # a[i][j][k]
