列表理解组合 2 个列表

Question

我有两个序列如下

t = [[1,2,3],[4,5,6],[7,8,9]]
alpha = ['a','b','c']

如何使用列表理解来修改 t 如下：-

t = [[1,2,3,'a'],[4,5,6,'b'],[7,8,9,'c']]

Answer 1

使用邮政编码：

t = [[1,2,3],[4,5,6],[7,8,9]]
alpha = ['a','b','c']
new_list = [a+[b] for a, b in zip(t, alpha)]

输出：

[[1, 2, 3, 'a'], [4, 5, 6, 'b'], [7, 8, 9, 'c']]
