如何在Python中反转列表? [英] How can I reverse a list in Python?

问题描述

如何在Python中执行以下操作?

How can I do the following in Python?

array = [0, 10, 20, 40]
for (i = array.length() - 1; i >= 0; i--)

我需要一个数组的元素，但是要从头到尾.

I need to have the elements of an array, but from the end to the beginning.

推荐答案

您可以使用

You can make use of the reversed function for this as:

>>> array=[0,10,20,40]
>>> for i in reversed(array):
...     print(i)

请注意，reversed(...)不会返回列表.您可以使用list(reversed(array))获得反向列表.

Note that reversed(...) does not return a list. You can get a reversed list using list(reversed(array)).
