Python 的re为什么匹配不到？正则表达式没错呀

import requests
import re


domain = "https://dy.dytt8.net/index2.htm"
resp = requests.get(domain, verify=False)
resp.encoding = "gb2312"

obj1 = re.compile(r"最新影片推荐.*?<ul>(?P<cont>.*?)</ul>", re.S)
obj2 = re.compile(r"<a href='(?P<href>.*?)'", re.S)
obj3 = re.compile(r'◎片　　名(?P<name>.*?)<br />.*?'
                  r'<a target="_blank" href="(?P<download>.*?)">', re.S)

result1 = obj1.finditer(resp.text)
child_href_list = []

for it in result1:
    ul = it.group('ul')

    # 提取子页面链接:
    result2 = obj2.finditer(ul)
    for itt in result2:
        # 拼接子页面的url地址:  域名 + 子页面地址
        child_href = domain + itt.group('href')
        child_href1 = child_href.replace("/index2.htm", "")
        child_href_list.append(child_href1) # 把子页面链接保存起来

for href in child_href_list:
    child_resp = requests.get(href, verify=False)
    child_resp.encoding = 'gb2312'
    result3 = obj3.search(child_resp.text)
    print(result3.group("movie"))
    print(result3.group("download"))

输出为

你打印下result1，得出来的不是个列表啊，finditer匹配还没用过，

看这个得到的是个对象，不能直接循环它，可以考虑用用findall
