缺少1个必需的位置参数，以及另一个和另一个

Question

我对Python非常陌生。为机器人编程，可以让它做一些事情，但不能做其他事情。我使用的许多变量都是在制造商提供的模块中定义的，其中一些会显示大量错误消息，如“缺少1个必需的位置参数”。如果我试图修复另一个出现，等等。因为我对这一点太陌生了，我不敢相信这真的是图书馆模块的错。它真的需要大量的修补，还是我出了什么问题

下面是我收到的几个错误消息：

    Microsoft Windows [Version 10.0.19041.985]

我正在编写的代码让机器人播放几个音符，闪烁灯光，然后沿着地板上标记的轨迹出发。声音和灯光都能正常工作，但它无法跟随轨道

#brings in external references

#controls the first robot, remember to update the com port number

    w = w+1

fa.ComClose(fa,7)
