我有以下代码，我的目标是在python中填充一个10x48数组。然而，数据取决于一个数据集，该数据集应在阵列中具有特定的位置。因此，我一直在为每个计算节点使用if语句来绘制它，但我想知道如何使用嵌套for循环在代码和内存中更快地绘制它。
共有48列和10行。
- 第一行每个计算节点都需要在计算1-1-0计算1-1-1计算1-1-2计算1-1-3计算1-2-0的范围内，直到1-12-3
- 下一行将具有相同的中间值，但最后的数字现在将使用数字4、5、6和7，因此例如它将变为计算1-1-4计算1-1-5计算1-1-6计算1-1-7计算1-2-4一直到1-12-7
这将持续到最后一行，最后一个数字将在36、37、38和39 之间旋转
所以计算1-1-36计算1-1-37计算1-1-38计算1-1-39计算1-2-36一直到1-12-39
下面的代码代表了我启动的if语句，但需要一种更有效的方法，这样我就可以节省内存，并消除在复制和粘贴时可能犯的任何错误。
