该问题采用非负整数和字符串列表并返回新的数字数组。

const filterlist = [1, 2, "a", "b", 0];

function filter_list(l) {
  let arrayResult = [];
  for (const iteml of l) {
    if (parseInt(iteml)) {
      arrayResult.push(iteml);
    }
  }
  return arrayResult;
}

const res = filter_list(filterlist);

for (let i = 0; i < res.length; i++) {
  console.log(res[i]);
}

// console.log(parseInt(0));

这样做时，结果发现只解析了 1 和 2，而 0 仍然悬而未决，但是为什么当我将转换带到控制台（注释行）时，它显示这是一个数字。我知道零是一个错误值，但是我该如何绕过它呢？

现在有了这个结果，如何让这一切不断发生呢？我们需要图片朝不同的方向移动。

const imagesOne = [
    'assets/img/main-1.jpg',
    'assets/img/main-2.jpg',
    'assets/img/main-3.jpg'
];

const imagesTwo = [
    'assets/img/main-4.jpg',
    'assets/img/main-5.jpg',
    'assets/img/main-6.jpg'
];

const boxOne = document.querySelector('.ag_main-right_one');
const boxTwo = document.querySelector('.ag_main-right_two');

imagesOne.forEach(src => {
    const img = document.createElement('img');
    img.className = 'ag_main-right_img';
    img.src = src;
    img.alt = 'main';
    boxOne.appendChild(img);
});

imagesTwo.forEach(src => {
    const img = document.createElement('img');
    img.className = 'ag_main-right_img';
    img.src = src;
    img.alt = 'main';
    boxTwo.appendChild(img);
});
.ag_main-right {
    height: 700px;
    overflow: hidden;
    position: relative;
    width: 100%;
    max-width: 574px;

        -webkit-transform: translateY(0);
        transform: translateY(0);
    }

    100% {
        -webkit-transform: translateY(-100%);
        transform: translateY(-100%);
    }
}

@keyframes scrollUp {

我正在用 Python aiogram3 编写一个电报机器人来玩测验。我需要测试它在几十/几百个用户的负载下如何工作，发送消息是否会出现延迟等。但我无法在任何地方找到有关如何执行此操作的信息。我发现的唯一信息是 Telegram 提供了以某种方式创建这些测试用户的能力，但没有提及如何做到这一点......
