我一直在做一个项目，使用 circuitpython 和 neopixels 作为学习如何使用板载计时器的一种方式。我已经完成了我的功能待办事项列表的 90%，现在我担心我可能需要重建整个事情来获得最后的 10%。
该项目旨在以萤火虫图案闪烁 n 个新像素。每种萤火虫图案都有一个功能。在脚本开始时，我创建了与灯光一样多的变量。然后我遍历它们，根据计时器打开或关闭灯。
我设法手动完成所有这些（根据有多少灯创建'variable_1，variable_2，...'），现在我试图根据灯的数量自动产生变量的数量。我还想在每次脚本启动时随机分配闪烁模式给灯光，但我认为这是最后一块。
正如您从下面的代码中看到的那样，我已经设法根据顶部的灯光数量自动创建变量。但是，当我尝试在底部的 while 循环中做类似的事情时，事情就崩溃了。我的问题基本上是“这就是存在类的原因，所以重写整个事情以使用类”？还是有其他方法可以使这项工作？
谢谢！
