第一个例子中，[0]这个列表被重复四次。第二个例子把列表[1，2，3]重复了三次。

The first example repeats [0] four times. The second example repeats the list[1, 2, 3] three times.

现在反方向重做一次，最上部到左边，然后是最底端到最右边，重复四次。如果感觉眼部有些累的话，就眨眼睛休息一下。

Now do the same thing in reverse, top left and bottom right, 4 times. Don't forget to blink and relax your eyes if they become too strained.
