[[' ' for _ in range(9)][i*3:(i+1)*3] for i in range(3)]

I've run this code in anaconda but how this thing worked I couldn't understand.
Can anyone please explain how does this little piece of code worked?

    Note that `[' ' for _ in range(9)][i*3:(i+1)*3]` is a particularly 'convoluted', to put it mildly, way to write `[' ', ' ', ' ']`. Not an example to follow in any way... – Thierry Lathuille May 29 '22 at 09:57
