列表中连续对的和，包括最后一个元素与第一个元素的和 [英] Sum of consecutive pairs in a list including a sum of the last element with the first

问题描述

我有一个像[1,3,5,6,8,7]这样的元素列表. 我想要一个列表中两个连续元素的和的列表，以使最后一个元素也与列表的第一个元素相加. 我的意思是在上述情况下，我需要此列表: [4,8,11,14,15,8]

I have a list of elements like [1,3,5,6,8,7]. I want a list of sums of two consecutive elements of the list in a way that the last element is also added with the first element of the list. I mean in the above case, I want this list: [4,8,11,14,15,8]

但是在for循环中添加最后一个元素和第一个元素时，索引超出范围. 考虑以下代码:

But when it comes to the addition of the last and the first element during for loop, index out of range occurs. Consider the following code:

List1 = [1,3,5,6,8,7]
List2 = [List1[i] + List1[i+1] for i in range (len(List1))]

print(List2)

推荐答案

List2 = [List1[i] + List1[(i+1)%len(List1)] for i in range (len(List1))]
