将两个 LISTS 值的 SUM 添加到新 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]
解决方案
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]
