Python-合并两个同时连接的列表 [英] Python - Merge two lists with a simultaneous concatenation

问题描述

ListA = [1,2,3]
ListB = [10,20,30]

我想将列表的内容加在一起(1+10,2+20,3+30)创建以下列表:

ListC = [11,22,33]

是否存在专门以这种方式合并列表的功能?

解决方案

这有效:

>>> ListA = [1,2,3]
>>> ListB = [10,20,30]
>>> list(map(sum, zip(ListA, ListB)))
[11, 22, 33]
>>>

在此处中说明了上面使用的所有内置函数. /p>

另一种解决方案是使用列表理解 .

根据您的口味，您可以这样做:

>>> [sum(x) for x in zip(ListA, ListB)]
[11, 22, 33]
>>>

或者这个:

>>> [x+y for x,y in zip(ListA, ListB)]
[11, 22, 33]
>>>

ListA = [1,2,3]
ListB = [10,20,30]

I want to add the contents of the lists together (1+10,2+20,3+30) creating the following list:

ListC = [11,22,33]

Is there a function that merges lists specifically in this manner?

解决方案

This works:

>>> ListA = [1,2,3]
>>> ListB = [10,20,30]
>>> list(map(sum, zip(ListA, ListB)))
[11, 22, 33]
>>>

All of the built-ins used above are explained here.

Another solution would be to use a list comprehension.

Depending on your taste, you could do this:

>>> [sum(x) for x in zip(ListA, ListB)]
[11, 22, 33]
>>>

or this:

>>> [x+y for x,y in zip(ListA, ListB)]
[11, 22, 33]
>>>
