在python中，如何在使用random()函数随机化后获取列表或数组或系列的原始顺序？

Question

I'm unable to get original order of list or array or series after randomizing them using random() function ? Please suggest some solution or different algorithm for the same.

Answer 1

One solution is:

import random

listA = [1,2,3,4]
listB = listA.copy()
random.shuffle(listA)
print(listA, listB)

You can also randomize using index only. It's useful when you want to avoid the manipulation of data.

import random

listA = ['A','B','C','D']

idxs = [i for i in range(len(listA))]
random.shuffle(idxs)

listB = [listA[i] for i in idxs]

print(listA, listB)
