如何实现python在虚拟环境GTA中自动驾驶程序的重启restart？

问题描述：

求救???? 大神们好，想请教一个问题，我现在和同学一起在写一个python项目, 是在GTA里实现自动驾驶汽车.代码中在 def button() 里面的 x.start() 会启动整个程序，我们还需要一个重启功能restart。现在不知道怎么restart x.start（）。

就是我们的这个程序有按钮 button 可以点一下开始键结束键现在需要弄好重新启动键。

有一个思路是重新调用一下x.start() 但是具体不知道怎么操作

谢谢????感激不尽！

重启restart做2步操作；

1.调用结束键对应的功能停止；

2.调用start函数功能启动。
