def get_photo_from_page():
    tut = []
    r = requests.get('https://vk.com/uporols_you').text
    soup = BeautifulSoup(r, 'lxml')
    im = soup.find_all('img', class_="ph_img")
    for a in im:
        s = a.get('data-src_big').split('|')[0]
        tut.append(s)
    y = "img%s.jpg"
    for t, im in tut, [y % i for i in range(1,5)]:
        p = requests.get(t)
        out = open(im, "wb")
        out.write(p.content)
        out.close()

def main():
    get_photo_from_page()

if __name__ == '__main__':
    main()

来自cmd的t，即tut，[y％i for i in range（1,5）]的错误： ValueError：解压缩的值太多（预期2）的＆GT;我需要列出1到1的URL累积，并通过possylke，并使用新名称保存所有图像，在不同的周期中，它始终获取最后一个可用的引用并将其存储为数字周期中显示的时间。
