如何在python中反转列表列表? [英] How to reverse a list of lists in python?

问题描述

我想知道如何在python中反转列表列表.例如

I was wondering how to reverse a list of lists in python. For example,

原文: list = [[1,2,3]，[4,5,6]，[7,8,9]] 输出: new_list = [[7,8,9]，[4,5,6]，[1,2,3]]

现在，我正在尝试:

new_list = reversed(list)

但是，这似乎不起作用.

However, this doesn't seem to work.

推荐答案

In [24]: L = [[1,2,3],[4,5,6],[7,8,9]]

In [25]: L[::-1]
Out[25]: [[7, 8, 9], [4, 5, 6], [1, 2, 3]]
