【问题描述】：
如果网站崩溃，有没有办法让这个机器人自动重启，如果网站没有正确加载，有没有办法让机器人刷新页面。因为我无法在刷新时获得 xpath，而且我不知道如果机器人没有完成目标，如何让机器人重新启动

如果您在代码中看到任何可以修复的内容，我们将不胜感激
【问题讨论】：

如果“重启机器人”意味着再次运行脚本，只需在代码周围添加一个带有“while True:”的
try except，并在完成时将其中断 -
但我认为这不是您真正的问题，因为您没有在代码中正确使用
try except。如果你只是不添加except子句，它在遇到错误时不会做任何事情，包括你想要的“重启”或重新执行 -
是的，那太好了...你能提供代码吗
-
如果是真的，你可以尝试：{把所有的东西都放在这里，然后休息} 除了：{print error}。
