题目描述

求三色彩球的颜色。有数量无限的红(Red)绿(Green)蓝(Blue)三种彩球排成一行，每组先为5个红色球，随后3个绿色，最后为2个蓝色。每个球都有编号，从左到右依次为1,2,3\dots\dots。输入整数代表编号，求该编号球的颜色。下面是Python代码的实现，正确说法是( )。 N = int(input()) remainder = N % 10 #remainder变量保存余数 if 1 <= remainder <= 5: print("Red") elif 6 <= remainder <= 8: print("Green") elif remainder == 9 or remainder == 0: print("Blue")

将 elif remainder == 9 or remainder == 0: 修改为 else 效果相同

将 if 1 <= remainder <= 5: 修改为 if remainder <= 5: 效果相同

elif 6 <= remainder <= 8: 写法错误，应修改为 elif 6 <= remainder and remainder <= 8:

根据题意 remainder = N % 10 应修改为 remainder = N // 10
