我是靠谱客的博主称心白昼，最近开发中收集的这篇文章主要介绍python爬百度文库课件，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

库:re;selenium;requests

源码：

from selenium import webdriver
import re
import requests

def open_img(items):
    for item in items:
        item = re.sub('&','&',item)
        rsp =requests.get(item)
        yield rsp.content

url ='https://wenku.baidu.com/view/4e3d35d969eae009581becd5.html?from=search'　　　　#可修改成别的ppt网址
browser =webdriver.Chrome()
try:
    browser.get(url)
    html =browser.page_source
    pattern =re.compile('<div class="ppt-page-item.*?src="(.*?)".*?>',re.S)
    items =re.findall(pattern,html)
    n =0
    for i in open_img(items):
        with open('%d.jpeg'%n,'wb') as file:
            file.write(i)·
            n +=1
            print('第%d张图片下载完成'%n)

finally:
    browser.close()
input()
