原理：通过selenium获取地址信息，再通过You-get批量下载

from selenium import webdriver
#from msedge.selenium_tools import EdgeOptions
#from msedge.selenium_tools import Edge
from selenium.webdriver.common.by import By

import time

edge_options = webdriver.EdgeOptions()
edge_options.use_chromium = True
# 设置无界面模式，也可以添加其它设置
edge_options.add_argument('--ignore-certificate-errors')
edge_options.add_argument('--ignore-ssl-errors')
edge_options.add_argument('--enable-chrome-browser-cloud-management')
#edge_options.add_argument('--headless')
# 还是有界面更好用些
driver = webdriver.Edge(options=edge_options)
#driver = Edge(options=edge_options)
driver.get('https://tv.cctv.com/lm/gzsbqlx/index.shtml')
for i in range(100):
    driver.execute_script(f'document.documentElement.scrollTop={(i+1)*1000}')
    time.sleep(2)
with open("yscj.txt",'w', encoding='utf-8') as f:
    page_source = driver.page_source
    f.write(page_source)
driver.quit()

再通过正则表达式获取地址，生成批量下载bat

import re

read_data = ""
with open('yscj.txt',encoding='utf-8') as f:
    read_data = f.read()

gzsb=r"(https://tv.cctv.com/\d{2}(?P<year>\d{2})/(?P<month>\d{2})/"  \
"(?P<day>\d{2})/[A-Za-z0-9]{24}(?P=year)(?P=month)(?P=day).shtml)"


tempres=re.findall(gzsb,read_data)

gzsblist=[]
for tempaddr  in tempres:
    if not tempaddr[0] in gzsblist:
        gzsblist.append(tempaddr[0])

gzsblist = sorted(gzsblist,reverse=True)

with open("yscj3.txt",'w+', encoding='utf-8') as f:
    for li in gzsblist:
        f.write("you-get "+ li + "\n")

或者使用bs解析出地址，生成you-get脚本

from bs4 import BeautifulSoup

read_data = ""
with open('yscj.txt',encoding='utf-8') as f:
    read_data = f.read()

soup = BeautifulSoup(read_data, 'lxml')
info = soup.find(id='boxList')
li_content = info.find_all('li')
with open("yscj2.txt",'w', encoding='utf-8') as f:
    for li in li_content:
        #link = li["href"]
        liimage = li.find('a')['href']
        f.write("you-get "+ liimage + "\n")
