Python 垂直阵列切片

Question

Can anyone show me how to slice the structure below:谁能告诉我如何分割下面的结构：

[[1, A], [2, B], [3,C]]

Into two separate lists:分成两个单独的列表：

[1, 2, 3]
[A, B, C]

I can obviously do this using code, but wondered if Python was able to do it natively?我显然可以使用代码做到这一点，但想知道 Python 是否能够在本地做到这一点？

Answer 1

my_list = [[1, A], [2, B], [3, C]]
a, b = zip(*my_list)

Note that a and b will end up being tuples.请注意， a和b最终将成为元组。
