先上代码:

#coding=utf-8
import urllib.request

for i in range(1,41):
   imgurl = "http://mtl.ttsqgs.com/images/img/11552/"
   imgurl += str(i) + ".jpg"
   urllib.request.urlretrieve(imgurl,'%s.jpg' % i)

这样短短的几行代码就把该网页上的图片全部下载下来了。怎样，是不是超级简单。

准备工作:

下载利器

urllib.request.urlretrieve

查看帮助

help(urllib.request.urlretrieve)

Help on function urlretrieve in module urllib.request:

urlretrieve(url, filename=None, reporthook=None, data=None)

    Retrieve a URL into a temporary location on disk.

    Requires a URL argument. If a filename is passed, it is used as

    the temporary file location. The reporthook argument should be

    a callable that accepts a block number, a read size, and the

    total file size of the URL target. The data argument should be

    valid URL encoded data.

    If a filename is passed and the URL points to a local resource,

    the result is a copy from local file to new file.

    Returns a tuple containing the path to the newly created

    data file as well as the resulting HTTPMessage object.

你只需要一个下载链接并设置好参数，即可下载。

图片分析:

网站: https://www.meitulu.com/item/11552.html

右键单击正文里的图片  —> 选择   查看图像信息。

http://mtl.ttsqgs.com/images/img/11552/1.jpg

再看看地址框类的图片，

http://mtl.ttsqgs.com/images/img/11552/2.jpg

http://mtl.ttsqgs.com/images/img/11552/3.jpg

http://mtl.ttsqgs.com/images/img/11552/4.jpg

这规律也是没谁了。

网站介绍

发行机构： 猫萌榜

期刊编号： Vol.023

图片数量： 40 张

也就是说最后一张的链接:

http://mtl.ttsqgs.com/images/img/11552/40.jpg

写出代码:

for i in range(1,41):        #半开半闭区间[1,41)

   imgurl = “http://mtl.ttsqgs.com/images/img/11552/”

   imgurl += str(i) + “.jpg”   #设置好链接，进行循环， str(i)将类型i转换为字符串

   urllib.request.urlretrieve(imgurl,’%s.jpg’ % i)     #下载到当前目录

当然，一般都需要查看下载进度,可以这样修改:

#coding=utf-8
import urllib.request

for i in range(1,41):
   imgurl = "http://mtl.ttsqgs.com/images/img/11552/"
   imgurl += str(i) + ".jpg"
   print ("正在下载第{}张图片".format(i))
   urllib.request.urlretrieve(imgurl,'%s.jpg' % i)
    
print ("OK!DownLoad ALL!")
