Grade letter
mark is 72. Print A for 80 and above, B for 70 to 79, C for 60 to 69, and D below that.
Order matters. Because Python stops at the first true test, checking >= 60 first would give C to every good mark. Start at the top and work down.

mark 是 72。80 及以上打印 A，70 到 79 打印 B，60 到 69 打印 C，再低打印 D。
顺序很重要。因为 Python 在第一个成立的判断处就停下，先判断 >= 60 会让所有高分都变成 C。要从高往低写。
