Pertama, dalam kod anda local=r'D:%s%s.jpg' % (nama fail,imgurl.splite("/")[-1])split ditulis sebagai splite local=r'D:%s%s.jpg' % (filename,imgurl.splite("/")[-1])中split写成了splite.

还有 urllib.request.urlretrieve(imgurl,local)这个imgurl不是一个合法的
url,只是一个相对 url, 要改成绝对 url,需要加上 base_url = 'http://www.shop2255.com/'

Juga urllib.request.urlretrieve(imgurl,local) imgurl ini bukan url
sah, hanya url relatif, Kepada tukar kepada url mutlak, anda perlu menambah base_url = 'http://www.shop2255.com/'

Nampaknya juga terdapat masalah dengan laluan fail yang dijana.🎜
