English
Upside-down triangle
Print four rows of stars, starting with four and ending with one.
range counts backwards with a negative step: range(3, 0, -1) gives 3, 2, 1. It still stops before its second number, which is why the stop value is 0.
中文
倒三角形
打印四行星星，从四颗开始，到一颗结束。
range 用负数步长就能倒着数：range(3, 0, -1) 给出 3、2、1。它仍然在第二个数之前停下，所以终止值写 0。
Print a triangle of stars that shrinks: ****, then ***, then **, then *. · 打印一个逐行变小的星星三角形：****、***、**、*。
