[求助]仿这鱼油写的爬取壁纸的代码，求帮看看问题在哪。

import urllib.request as ur
import re
import os

def open_url(url):
    req = ur.Request(url)
    req.add_header('User-Agent','Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36')
    response = ur.urlopen(req)
    html = response.read()
    return html
   

def find_imgs(url):
    html = open_url(url).decode('gbk')
    img_addr = re.findall(r'<img src="([^"]*\.jpg)"',html)
    print(img_addr)
    return img_addr

def save_imgs(img_addr):
    for each in img_addr1:
        os.chdir('pictrue')
        filename = each.split('/')[-1]
        with open(filename,'wb') as f:
            img = open_url(each)
            f.write('img')
            


def down_bz():
    filename = 'pictrue'
    os.mkdir(filename)
    url = 'http://pic.netbian.com/4kdongman/'
    open_url(url)
    find_imgs(url)
    save_imgs(img_addr)

if __name__ == '__main__':
    down_bz()

塔利班

img_addr = re.findall(r'<img src="([^"]*\.jpg)"',html)应该是非贪婪吧
img_addr = re.findall(r'<img src="([^"]*?\.jpg)"',html)
其他没看

报错时NameError:img_addr is not defined

塔利班

def down_bz():
    filename = 'pictrue'
    os.mkdir(filename)
    url = 'http://pic.netbian.com/4kdongman/'
    open_url(url)
    find_imgs(url)
    save_imgs(img_addr)
这段应该是
def down_bz():
    filename = 'pictrue'
    os.mkdir(filename)
    url = 'http://pic.netbian.com/4kdongman/'
    save_imgs(find_imgs(url))
