好的,以下是Python代码,可以随机生成十道两个三位数的加减乘除法运算题目,并在两分钟内计算完成。如果计算未完成或分数低于60分,则电脑会自动关机。
```python
import random
import time
import os
def generate_question():
# 随机生成两个三位数和运算符号
num1 = random.randint(100, 999)
num2 = random.randint(100, 999)
operator = random.choice(['+', '-', '*', '/'])
# 根据运算符号生成题目
if operator == '+':
answer = num1 + num2
elif operator == '-':
answer = num1 - num2
elif operator == '*':
answer = num1 * num2
elif operator == '/':
answer = num1 // num2
num1 = answer * num2 # 避免出现小数
question = f"{num1} {operator} {num2} = "
return question, answer
def calculate_score(num_correct, total_questions):
# 计算分数并返回
score = num_correct / total_questions * 100
return score
def main():
# 初始化变量
num_correct = 0
total_questions = 10
questions = []
answers = []
# 生成题目
for i in range(total_questions):
question, answer = generate_question()
questions.append(question)
answers.append(answer)
# 开始计时
start_time = time.time()
# 让用户回答题目
for i in range(total_questions):
print(f"第{i+1}题:{questions[i]}")
user_answer = input("请输入答案:")
if int(user_answer) == answers[i]:
print("回答正确!")
num_correct += 1
else:
print("回答错误!")
# 计算分数
score = calculate_score(num_correct, total_questions)
# 输出结果
print(f"\n您一共回答了{total_questions}道题,其中{num_correct}道题回答正确。")
print(f"您的分数为:{score:.2f}分")
# 判断是否需要关机
if score < 60 or time.time() - start_time > 120:
os.system("shutdown -s -t 0")
print("电脑将在30秒后关机!")
else:
input("按任意键退出。")
if __name__ == "__main__":
main()
```
运行程序后,它会随机生成十道两个三位数的加减乘除法运算题目,并要求用户在两分钟内回答完毕。如果用户回答正确,则会提示“回答正确!”;如果回答错误,则会提示“回答错误!”;如果时间到了两分钟或分数低于60分,则电脑会自动关机。如果用户在规定时间内回答完毕并且分数高于等于60分,则程序会等待用户按任意键退出。
