用Python减去2个列表 [英] Subtracting 2 lists in Python

问题描述

现在，我将vector3值表示为列表.有没有一种方法可以减去其中两个类似的vector3值，例如

Right now I have vector3 values represented as lists. is there a way to subtract 2 of these like vector3 values, like

[2,2,2] - [1,1,1] = [1,1,1]

我应该使用元组吗?

如果没有一个在这些类型上定义这些操作数，我可以改为定义它吗?

If none of them defines these operands on these types, can I define it instead?

如果没有，我应该创建一个新的vector3类吗?

If not, should I create a new vector3 class?

推荐答案

如果您经常这样做，并且使用不同的操作，则可能应该创建一个类来处理此类情况，或者最好使用类似的库 Numpy .

If this is something you end up doing frequently, and with different operations, you should probably create a class to handle cases like this, or better use some library like Numpy.

否则，请查找与列表理解 ="http://docs.python.org/library/functions.html#zip" rel ="noreferrer"> zip 内置函数:

Otherwise, look for list comprehensions used with the zip builtin function:

[a_i - b_i for a_i, b_i in zip(a, b)]
