Question

将值列表分配给具有不同索引的2D列表的最佳方法是什么？

temp_list = [2, 1, 1, 5]

我想遍历2D列表：

list_to_assign =
          [[0, 0, 0, 0],
           [0, 0, 0, 0],
           [2, 0, 0, 1000],
           [0, 0, 0, 0]]

对于temp_list的每个值，我想将该值分配给2D列表中每个内部列表的零索引。

我想要的结果是

[[2, 0, 0, 0],
[1, 0, 0, 0],
[1, 0, 0, 1000],
[5, 0, 0, 0]]

Answer 1

IIUC，请尝试在下面使用此列表理解：

print([[x] + y[1:] for x,y in zip(temp_list,list_to_assign)])

输出：

[[2, 0, 0, 0], [1, 0, 0, 0], [1, 0, 0, 1000], [5, 0, 0, 0]]
