如何以python降序对整数列表进行排序 [英] How to sort integer list in python descending order

问题描述

我试图以不同的方式解决这个问题，但没有成功.打印时，我一直保持升序排序，而不是降序.

I have tried to figure this out in different ways, to no success. I keep getting ascending order sort, rather than descending order when I print.

ListB = [24, 13, -15, -36, 8, 22, 48, 25, 46, -9]
sorted(ListB, key=int, reverse=True)
print sorted(ListB)

推荐答案

您正在打印升序排列的列表:

You are printing the list sorted ascending:

print sorted(ListB)

如果您希望它降序，请将打印语句放在前一行(在此处反转)

If you want it descending, put your print statement on the previous line (where you reverse it)

print sorted(ListB, key=int, reverse=True)

然后删除您的最终打印声明.

Then remove your final print statement.

示例:

>>> ListB = [24, 13, -15, -36, 8, 22, 48, 25, 46, -9]
>>> print sorted(ListB, key=int, reverse=True)
[48, 46, 25, 24, 22, 13, 8, -9, -15, -36]
