如何启动和终止正在运行的线程？

我目前正在编写自己的小型网络爬虫程序，尝试实现在将URL添加或从列表中删除时启动和终止线程的功能。目前我已经创建了以下代码：

import concurrent.futures
import time
import random
import requests
class WebScraper:
    def __init__(self):
        self.session = requests.Session()
    def run(self, url: str):
        while True:
            response = self.do_request(url)
            if response.status_code != 200:
                continue
            data = self.scrape_data(response)
            ...
            time.sleep(500)
    def do_request(self, url):
        response = self.session.get(url)
        return response
    def scrape_data(self, response):
        # TODO: 在这里实现你的网络爬虫逻辑
        return {}
if __name__ == '__main__':
    URLS_TO_TEST = [
        "http://books.toscrape.com/catalogue/category/books/travel_2/index.html",
        "http://books.toscrape.com/catalogue/category/books/mystery_3/index.html",
        "http://books.toscrape.com/catalogue/category/books/historical-fiction_4/index.html",
        "http://books.toscrape.com/catalogue/category/books/sequential-art_5/index.html",
        "http://books.toscrape.com/catalogue/category/books/classics_6/index.html",
    ]
    with concurrent.futures.ThreadPoolExecutor() as executor:
        for url in URLS_TO_TEST:
            session = WebScraper()
            future = executor.submit(session.run, url)
    time.sleep(random.randint(10, 20))
    URLS_TO_TEST.pop(random.randint(0, len(URLS_TO_TEST) - 1))  # 删除的URL也应该终止线程
    time.sleep(random.randint(10, 20))
    URLS_TO_TEST.append('http://books.toscrape.com/catalogue/category/books/health_47/index.html')  # 添加的URL也应该启动新线程

我的问题是，我不确定是否可以在从主列表中删除URL时终止正在运行的线程，反之亦然。是否可以使用线程来实现这个功能？

以后的想法是通过数据库来设置URL_TO_TEST，而不是使用静态列表，并且将会动态更新，但这将在以后进行。
