1.自定义的进度条，拿去用

# 自己写一个进度条

    :param counts: 总量

    :param key: 进度条字符
    :param second: 刷新间隔
    :return:
    """
    if count <= counts:

        count_str = count_str.ljust(length, " ")
        percentage = round(count / counts * 100, 2)
        s = f"[{count_str}] {percentage}% | {round(count, 2)}/{round(counts, 2)}"
        print(f"\r{s}", end="")
        time.sleep(second)
        if percentage == 100:
            print()
    else:

        progress(count,counts)
