from concurrent.futures import ThreadPoolExecutor
import requests
import re
import time


def main():
    m3u8_url = get_m3u8_url()
    get_m3u8_file(m3u8_url)
    get_video()


def get_m3u8_url():
    com = re.compile(r'"link_pre":"","url":"(?P<m3u8_url>.*?)","url_next', re.S)
    url = "https://www.yunbtv.net/vodplay/youyuyouxi-1-1.html"
    requ = requests.get(url)
    m3u8_url = com.search(requ.text).group("m3u8_url")
    m3u8_url = m3u8_url.replace("\\", "")
    return m3u8_url


def get_m3u8_file(m3u8_url):
    with open("鱿鱼游戏/m3u8/1.m3u8", mode="wb") as f_1:
        f_1.write(requests.get(m3u8_url).content)

            if line.startswith("#"):
                continue
            else:

    with open("鱿鱼游戏/m3u8/1.m3u8", mode="wb") as f_3:
        f_3.write(requests.get(second_url).content)


def get_video():
    i = 1
    with ThreadPoolExecutor(50) as threadpool:
        with open("鱿鱼游戏/m3u8/1.m3u8", mode="r", encoding="utf-8") as f:

                else:

                    threadpool.submit(get_download_ts, line, i)
                i = i+1


def get_download_ts(line, i):

    with open("鱿鱼游戏/ts/第1集/{}.ts".format(i), mode="wb") as f:
        f.write(requests.get(line).content)
        print("第1集/{}.ts下载完成---".format(i))
        time.sleep(0.3)


# "https://ts8.hhmm0.com:9999/20210917/ahQ89ILO/1000kb/hls/key.key"



if __name__ == "__main__":
    # start_time = time.time()
    main()
    # end_time = time.time()
    # print("下载完成，用时{:.2f}秒".format(end_time-start_time))

运行结果及报错内容

无报错，也无结果，程序也不停止，所有ts文件都已经下载完成

第1集/909.ts下载完成---
第1集/898.ts下载完成---
第1集/1036.ts下载完成---
第1集/700.ts下载完成---

我的解答思路和尝试过的方法

我想要达到的结果

完整运行

ts文件太多了，你得跑好久,一个两小时的视频，一个ts文件只有两三秒五六秒，所以说大概有好几千个ts文件需要爬，让它慢慢跑吧，如果反扒处理都没有问。有帮助的话采纳一下哦🙈🙈🙈
