python随机出5个两整数相加题，统计出答题正确的时间

下面是一个示例代码，你可以根据你的需要进行修改：

import random
import time

def generate_questions(num):
    questions = []
    for i in range(num):
        a = random.randint(1, 100)
        b = random.randint(1, 100)
        questions.append((a, b))
    return questions

def ask_questions(questions):
    correct_count = 0
    start_time = time.time()
    for a, b in questions:
        answer = input(f"What is {a} + {b}? ")
        if int(answer) == a + b:
            correct_count += 1
    end_time = time.time()
    return correct_count, end_time - start_time

questions = generate_questions(5)
correct_count, time_taken = ask_questions(questions)

print(f"You got {correct_count} out of {len(questions)} questions correct.")
print(f"Total time taken: {time_taken:.2f} seconds")

这个代码会生成 5 个两整数相加题，然后让用户回答这些问题，并统计答题正确的数量和总时间。
