为什么我的程序Professor.py没有通过check50？ CS50 Python 问题集 4 - 小教授

Question

我尝试了一切，但似乎找不到问题所在。当我正常运行程序时，它会为我提供所有内容的正确输出。我无法理解 check50 的错误 以下是所需的规范：https://cs50.harvard.edu/python/2022/psets/4/professor/

import random


def main():
    level = get_level()
    score = 0
    for i in range(10):
        problem = generate_integer(level)
        list = problem.split("=")
        prob = list[0]
        ans = list[1]
        ans = int(ans)
        answer = input(prob + "= ")
        if answer.isdigit():
            answer = int(answer)
        else:
            print("EEE")
            continue
        if answer != ans:
            print("EEE")
            answer1 = input(prob + "= ")
            answer1 = int(answer1)
            if answer1 == ans:
                score += 1
                continue
            if answer1 != ans:
                print("EEE")
                answer2 = int(input(prob + "= "))
                if answer2 == ans:
                    score += 1
                else:
                    print(prob + "= " + list[1])
                    continue
        else:
            score += 1
    print("Score:", score)


def get_level():
    while True:
        level = input("Level: ")
        if level.isdigit():
            level = int(level)
        else:
            continue
        if level != 1 and level != 2 and level != 3:
            continue
        else:
            break
    return level


def generate_integer(level):
    problem = ""
    if level == 1:
        X = random.randint(1, 9)
        Y = random.randint(1, 9)
    elif level == 2:
        X = random.randint(10, 99)
        Y = random.randint(10, 99)
    elif level == 3:
        X = random.randint(100, 999)
        Y = random.randint(100, 999)
    problem = f"{X} + {Y} = {X+Y}"
    return problem

if __name__ == "__main__":
    main()

我看到其他问题使用random.seed()，但在这里我从未使用random.seed()

Answer 1

这段代码

X = random.randint(1, 9)
Y = random.randint(1, 9)

不会“使用 0-9 产生加法问题”
