python - 如何在Python中反转列表？(How can I reverse a list in Python?)

Question

How can I do the following in Python?

(如何在Python中执行以下操作？)

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

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

(我需要一个数组的元素，但是要从头到尾。)

Answer 1

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

(您可以通过以下方式使用reversed功能：)

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

Note that reversed(...) does not return a list.

(请注意， reversed(...)不会返回列表。)

You can get a reversed list using list(reversed(array)) .

(您可以使用list(reversed(array))获得反向列表。)
