将两个 LISTS 值的 SUM 添加到新 LIST [英] Add SUM of values of two LISTS into new LIST

问题描述

我有以下两个列表:

first = [1,2,3,4,5]
second = [6,7,8,9,10]

现在我想将这两个列表中的项目添加到一个新列表中.

Now I want to add the items from both of these lists into a new list.

输出应该是

third = [7,9,11,13,15]

推荐答案

zip 函数在这里很有用，与列表推导一起使用.

The zip function is useful here, used with a list comprehension.

[x + y for x, y in zip(first, second)]

如果您有一个列表列表(而不仅仅是两个列表):

If you have a list of lists (instead of just two lists):

lists_of_lists = [[1, 2, 3], [4, 5, 6]]
[sum(x) for x in zip(*lists_of_lists)]
# -> [5, 7, 9]
