] | It means a list of `None`s with a `height` number of elements. e.g., for `height = 3`, it is this list:
```
[None, None, None]
``` | ```
>>> [None] * 5
[None, None, None, None, None]
```
Gives you a list of size `height` in your case |

] | If you do -
```
[element] * 3
```
You get -
```
[element, element, element]
```
That's what the code does, `[None] * height`
That is, if -
```
height = 4
[None] * height
# equals [None, None, None, None]
``` | ```
>>> [None] * 5
[None, None, None, None, None]
```
