用Python编写一个随机出5个两整数相加题，统计出答题正确的题数和用时

可以使用random库来生成随机数，time库来计算答题用时。下面是代码实现：

import random
import time

correct_count = 0  # 记录答题正确的数量
start_time = time.time()  # 记录开始时间

for i in range(5):
    num1 = random.randint(1, 100)  # 生成随机数1
    num2 = random.randint(1, 100)  # 生成随机数2
    result = num1 + num2  # 计算结果

    # 提示用户输入答案，并转为int类型
    answer = int(input(f"What is {num1} + {num2}? "))

    # 判断答案是否正确
    if answer == result:
        print("Correct!")
        correct_count += 1
    else:
        print("Incorrect!")

end_time = time.time()  # 记录结束时间
total_time = end_time - start_time  # 计算总用时

print(f"\nYou got {correct_count} out of 5 questions correct.")
print(f"Total time: {total_time:.2f} seconds")

运行示例：

What is 35 + 47? 82
Correct!
What is 19 + 65? 84
Incorrect!
What is 73 + 94? 167
Correct!
What is 5 + 77? 82
Correct!
What is 95 + 6? 101
Correct!

You got 4 out of 5 questions correct.
Total time: 15.22 seconds
