在上述代码中,long_running_function是一个无限循环的函数,永远不会结束。然而,我们设置了超时时间为5秒,所以在5秒后,超时处理函数会被触发,抛出一个TimeoutError异常。 总结 Python函数的超时机制允许我们在特定时间内执行操作,并在超时时终止它。通过使用signal模块,我们可以轻松地实现超时机制。在代码中,我们可以定...

3、使用python第三方 func_timeout 模块中提供的 func_set_timeout 装饰器可以非常简单的设置python程序的超时时间,超时后程序抛出 func_timeout.exceptions.FunctionTimedOut 异常。此时再用 try-except 做异常处理即可。 安装模块 pip install func_timeout ...
# Call the function to start the timeout timeout(12) 这个代码示例中的timeout函数会在开始时记录当前时间start_time,然后在循环中每秒检查一次当前时间current_time是否超过了设定的超时时间seconds。如果超过了设定的时间,那么就会打印一条消息并退出循环。你可以将这个函数替换为你自己的操作,比如等待特权提升提示...
