Question

我已经编写了一个python3.x脚本来从matplotlib绘制图，并且tkinter用于对话框窗口中输入标题，然后浏览要使用的数据文件。经过大量测试后，一切都按我的要求运行，除了关闭绘图窗口后程序仍在运行。我必须关闭终端窗口或在Ipython / jupyter中重置内核。 pyplot关闭时，有没有一种简单的方法可以终止程序？

注意，我真的是编程新手，其中很多都是通过教程和其他论坛问题组合而成的。我在想一个可能的问题是我的后端方式（matplotlib说use（）不是首选的方式），也许可以通过建立一个循环来询问是否要创建另一个循环来找到解决方案。情节。另一种可能性是将绘图放入tkinter窗口，但老实说，我今天刚刚教自己tkinter，这是打开浏览器选择数据文件的一种方式。

我使用linux命令执行此操作，它显示了所有打开的python进程，然后使用其PID杀死了它

ps aux | grep python
kill 1234
