python3.7脚本---爬取网页图片

#!/usr/bin/python

import re
import urllib
import urllib.request   #python3中urlopen、urlritrieve都在request库里面了,所以要导入此库

def htmlGet(url):
        page = urllib.request.urlopen(url)
        html = page.read()
        return html

def imgGet(html):
        res = r'src="(https.*?\.jpg)"'
        imgre = re.compile(res)
        imglist = re.findall(imgre,html.decode("utf-8")) #html不加后面的会报错typeerror,因为编码格式的变化,这里需要指定一下
        x = 0
        for i in imglist:
                urllib.request.urlretrieve(i,"%s.jpg" % x)
                x+=1
