Python 随机算术题练习 - 加减乘除，三次机会

import random

score = 0 for i in range(4): num1 = random.randint(0, 100) num2 = random.randint(0, 100) operator = random.choice(['+', '-', '*']) answer = eval(str(num1) + operator + str(num2)) print('第%d题：' % (i+1)) for j in range(3): guess = input('请回答 %d %s %d = ' % (num1, operator, num2)) if int(guess) == answer: print('回答正确！') score += 10 break else: print('回答错误，请重新作答！') else: print('本题答案为 %d' % answer)

print('您的最终得分为：%d' % score)
