while True:
a = random.randint(0, 9)
# 作为除数
b = random.randint(1, 9)
op = [‘+‘, ‘-‘, ‘*‘, ‘//‘]
d = random.choice(op)

question = input(‘请输入您的答案： （q退出）‘)
result1 = a + b
result2 = a - b
result3 = a * b

right += 1
count += 1

percent = right / count
print(‘测试结束,共回答%d道题,正确个数为%d,正确率为%.2f%%‘
% (count, right, percent * 100))
