another wallpaper

还是壁纸，这次的图片来自彼岸网，上面有各种4K高清壁纸。

代码

还是用request获取内容，用lxml解析。具体如下：

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import random
import tempfile

import requests
import win32api
import win32con
import win32gui

        self.image = os.path.join(tempfile.gettempdir(), "wallpaper.jpg")

    def crawl(self):
