更好的方式来洗牌两个相关的列表 6个答案

假设我有一个列表A并对其进行了改组：

import random random.shuffle(A)

现在我用随同排列洗牌seconf列表B ，就像shuffle应用到A 。

这怎么可能？

大熊猫呢？

This question already has an answer here:

Better way to shuffle two related lists 6 answers

Suppose I have a list A and shuffled it:

import random random.shuffle(A)

Now I with to shuffle the seconf list B with THE SAME permutation, as was applied by shuffle to A.

How is it possible?

What about pandas?

您可以在洗牌之前将列表压缩，然后将其解压缩。 这不是特别有效的内存（因为你在洗牌过程中基本上是复制列表）。

a = [1,2,3] b = [4,5,6] c = zip(a, b) random.shuffle(c) a, b = zip(*c)

You could zip the lists before shuffling, then unzip them. It's not particularly memory efficient (since you're essentially copying the lists during the shuffle).

a = [1,2,3] b = [4,5,6] c = zip(a, b) random.shuffle(c) a, b = zip(*c)
