我正在编写一个代码,基本上为了移动性和功能而没有循环运行。让我们说当我运行程序时,我使用-i选项继续使用python解释器,因为它加载了所有写入的函数。事情是,我在程序打印一些基本信息后使用类似功能的屏幕保护程序,使其看起来不那么无聊。
我的问题是:如何在不阻止解释器提示的情况下保持屏幕保护程序运行。我已经写过如何处理键盘输入以使用curses“getch()”来停止它。我尝试使用线程,但没有用,因为它没有检测到任何键盘输入,所以它一直在运行。
有什么方法可以解决这个问题吗?如何在不阻塞的情况下检测任何输入,从而保留解释器提示符?
知道它检测到一个输入并引发一个KeyboardException,以使屏幕保护程序停止。
提前致谢
我正在使用此代码并添加一些修改: Matrix-Curses
到目前为止我所拥有的: Completed Code
