如何从一个列表分配到另一个列表? [英] How to assign from one list to another?

问题描述

如果我有3个列表

List1 = ["A","B","C"] 
List2 = [1,2,3]
List3 = [4,5,6]

如何分配和汇总List2&从List3到List1，以便

How can I assign and sum List2 & List3 to List1 so that

A = 5
B = 7
c = 9

推荐答案

使用字典理解:

>>> {key: a + b for key, a, b in zip(List1, List2, List3)}
{'A': 5, 'C': 9, 'B': 7}

我必须承认你的问题令人困惑.也许您正在寻找替代品?

I must admit your question was confusing. Maybe you are looking for this instead?

>>> List1 = [a + b for a, b in zip(List2, List3)]
>>> List1
[5, 7, 9]
