## 1、全代码 ##

import requests
    from selenium import webdriver
    import os
    
    wd = webdriver.Chrome(r'D:\tools-work\chromedriver_win32\chromedriver.exe')
    
    wd.implicitly_wait(5)
    
    # wd.get(f'https://www.szzhdj.gov.cn/views/learn/details.html?type=video&id=e02e7f58f5314d968ef6a9862fa9272b')
    wd.get(f'https://www.szzhdj.gov.cn/views/learn/details.html?type=video&id=283c0759306c41c8bf738552a9f83b19')
    # #标题
    # text = wd.find_elements_by_xpath('//*[@id="app"]/main/section/main/article/p/span')
    
    #标题
    title = wd.find_element_by_css_selector('#app > main > section > main > h1')
    # print(title.text)
    # for x in content:
        # print(x.text)
    
    # 视频
    MP4 = wd.find_element_by_css_selector('#initVideo > div > video')
    # for y in MP4:
    URL = MP4.get_attribute('src')
    # print(URL)
    m = requests.get(URL)
    # # for r in range(3):
    path = 'D://党建视频//'+ f'{title.text}'+'.mp4'
    with open(path, 'wb') as f:
        f.write(m.content)
    #封面视频
    img = wd.find_element_by_css_selector('#initVideo > div > div.vcp-poster > img')
    # for y in MP4:
    URL1 = img.get_attribute('src')
    # print(URL)
    m1 = requests.get(URL1)
    # # for r in range(3):
    path2 = 'D://党建视频封面//'+ f'{title.text}'+'.png'
    with open(path2, 'wb') as f:
        f.write(m1.content)
    
    quit()

2、分析  
2.1 用selenium 取出新闻的标题、视频、封面图片等信息  
2.2 用requets库取出视频和图片等信息

参考是关于视频和图片的获取法子
