python - 给定另一个索引号列表，将数字插入列表

我正在根据索引号列表（indexNumberList）将数字列表（firstNumberList）插入另一个列表（secondNumberList）中的特定点。

indexNumberList = [1, 2, 5, 8]
firstNumberList = [0, 0, 0, 0]
secondNumberList = [ 3, 1, 3, 2, 4, 1, 1, 4, 4, 4, 9, 9, 12, 12, 18, 19, 18, 9]

我已经尝试了以下列表理解，但它返回[none, none, none, none]

result =[secondNumberlist.insert(indexNumberList[elem],firstNumberList[elem]) for elem in range(len(indexNumberList))]

最终输出应如下所示

[ 3, 0, 0, 1, 3, 0, 2, 4, 0, 1, 1, 4, 4, 4, 9, 9, 12, 12, 18, 19, 18, 9]

最佳答案

indexNumberList = [1, 2, 5, 8]
firstNumberList = [0, 0, 0, 0]
secondNumberList = [3, 1, 3, 2, 4, 1, 1, 4, 4, 4, 9, 9, 12, 12, 18, 19, 18, 9]

for i, v in zip(indexNumberList, firstNumberList):
    secondNumberList = secondNumberList[:i] + [v] + secondNumberList[i:]

print(secondNumberList)

印刷品：

[3, 0, 0, 1, 3, 0, 2, 4, 0, 1, 1, 4, 4, 4, 9, 9, 12, 12, 18, 19, 18, 9]

编辑：带有list.insert的版本（感谢@Chris_Rands）：

for i, v in zip(indexNumberList, firstNumberList):
    secondNumberList.insert(i, v)
