Python 使用序列设置数组元素

我试图对mcedit过滤器进行扩展，最初由CrushedPixel编写，由NanoRex编辑。他们制作的版本不支持1.9快照/块，所以我决定制作一个更好的、无延迟的版本

代码如下：

这给了我一个错误：用senquence设置数组元素。 下面是一些屏幕，显示了它的用途和问题：

, . 好了，现在我知道问题的原因了。我怎样才能解决它？我真的很想让它工作：l

C=C'，D创建一个序列，比如，'，所以当你在做schematic.setBlockAtx，y，z，C时，你的C参数是一个序列，当它需要一个单独的项时。

我怎么解决这个问题？昨天我第一次尝试python，对不起。@kratenko:
