设计一个程序,帮助小学生练习10以内的加法
详情:
- 随机生成加法题目;
- 学生查看题目并输入答案;
- 判别学生答题是否正确;
- 退出时,统计学生答题总数,正确数量及正确率(保留两位小数)。

更新一种很简单的代码:
看了老师的代码,服了自己,哈哈哈哈
import random
rightCount = 0
print("小学生算术测试系统".center(50,"*"))
totalCount = int(input("请输入所需要的题目数量:"))
for count in range(totalCount):
num_1 = random.randint(1,10)
num_2 = random.randint(1,10)
sum_ = num_1 + num_2
print("第%d题: %d + %d = " %(count+1,num_1,num_2),end = ' ')
userRes = int(input())
if userRes == sum_ :
rightCount += 1
print("OK")
else :
print("wrong")
else:
print("测试结果".center(50,'*'))
print("答对数量: %d" %(rightCount))
print("正确率: %.2f%%" %(rightCount/totalCount*100))
