python selenium在多线程情况下，中途执行失败视窗虽已关闭仍在任误管理器背景执行

Question

各位好
我的程序在跑到一半抱错时仍会在背景执行
这是因为线程没有被删除吗
因为我目前都是把 driver.quit() 这种挂在程式码的最后边
所以他得要全部流程都跑对才有办法关闭
想请问我该如何在程序失败时将线程完全关闭()
谢谢

    driver = webdriver.Chrome(service = ser,options=chrome_options)

    driver.quit()

今天可能在按下button 1 失败然后就报错关闭了
但有时在任务管理器背景还是存在WebChrome

Answer 1

报错了也不应该关闭
代码崩溃是因为你没有加try，except
该加错误捕获的地方都要加上
你主程序都关闭了，谁来监视子线程啊
