import requests
from requests import Session
from bs4 import BeautifulSoup
import re
from multiprocessing.dummy import Pool as ThreadPool

#s = Session()

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 的错误 for t, im in tut, [y % i for i in range(1,5)]: ValueError：要解包的值太多（预期为 2） > 我需要列出 1 对 1 的 URL，并在段落 possylke 上，并以新名称保存所有图像，在单独的周期中，它总是获取最后一个可用的引用并将其存储为循环中指示的时间。

#s = Session()

def get_photo_from_page():

    r = requests.get('https://m.vk.com/uporols_you').text
    soup = BeautifulSoup(r, 'lxml')
    im = soup.find_all('img', class_="ph_img")
    try:

            tut.append(s)
        print(tut)  
    except:
        print('no have any links)')

    for num, link in enumerate(tut, start=1):
        p = requests.get(link)
        out = open("img%s.jpg" % (num), 'wb')
        out.write(p.content)
        out.close()

def main():
    get_photo_from_page()

if __name__ == '__main__':
