爬取页面web端效果图
有没有让你看的怦然心动，我是觉得清纯的妹纸挺好的。
2.2 爬取方式：简单 or 困难
爬取方式分析
3.1 从简单开始：首先我们要获取这个页面上的所有妹纸图的链接（一个妹纸有多张艺术照），然后向网站发送相应链接的请求，浏览器内按F12，进入开发者模式，小箭头选择想要的信息所在处。
页面分析获取内容所在
3.2 分析我们拿到的页面源码，采用正则表达式获取相关内容
源码分析采用什么正则匹配
3.3 正则表达式获取首页所有妹纸图的网址和简介

4pictures_url = re.findall(pattern04, picture_words)

3.6 下载图片
3.6.1 专门写个下载图片函数
1# 下载图片函数
2'''
3folder_name : 分类文件夹名称，按图片简介
4picture_address ： 一组图片的链接
5'''
6def download_pictures(folder_name, picture_address):
7 file_path = r'G:Beautiful{0}'.format(folder_name)
8 if not os.path.exits(file_path):
9 # 新建一个文件夹
10 os.mkdir(os.path.join(r'G:Beautiful', folder_name))
11 # 下载图片保存到新建文件夹
12 for i in range(len(picture_address)):
13 # 下载文件（wb,以二进制格式写入）
14 with open(r'G:Beautiful{0}{1}.jpg'.format(folder_name,i+1), 'wb') as f:
15 # 根据下载链接，发送请求，下载图片
16 response = requests.get(picture_address[i][0])
17 f.write(response.content)
3.6.2 运行结果
运行结果
爬取结果（文字有点露骨）
单组皂片示例，看图片大小，挺清晰的
4. 上面只是爬取了主页面的所有妹纸图片，如何实现在主页面翻页呢？
希望大家根据在单个妹子网页翻页的方法（3.5），自己动手写出如何在主页面翻页，爬取更多妹纸图！
实现下图页面翻页
