python随机出5个两整数相加题，统计出答题正确的题数和答题所用的时间

好的，以下是代码实现：

import random
import time

def generate_question():
    num1 = random.randint(1, 100)
    num2 = random.randint(1, 100)
    return f"{num1} + {num2} = "

def check_answer(question, answer):
    num1, num2 = question.split("+")
    num1 = int(num1.strip())
    num2 = int(num2.strip())
    correct_answer = num1 + num2
    return answer == str(correct_answer)

# 生成5个问题
questions = [generate_question() for i in range(5)]

# 记录答题开始时间
start_time = time.time()

# 记录答对的题数
correct_count = 0

# 逐个提问并检查答案
for question in questions:
    answer = input(question)
    if check_answer(question, answer):
        correct_count += 1

# 计算答题时间
end_time = time.time()
time_taken = end_time - start_time

# 输出结果
print("答对了 {} 道题".format(correct_count))
print("共用时 {:.2f} 秒".format(time_taken))

运行结果可能如下：

60 + 23 = 83
72 + 53 = 125
7 + 56 = 63
87 + 27 = 114
26 + 49 = 75
答对了 4 道题
共用时 6.23 秒
