Question

I have the two lists in Python

list_1 = [5, 2, 8];
list_2 = ['string1', 'string2', 'string3']

I would like to sort the fist list and use the result to sort the second list.

In other words, the result should be:

# Sorted in descending order
list_1_sorted = [8, 5, 2];
list_2_sorted = ['string3', 'string1', 'string2'];

I know how to sort each of these lists individually, but how I can permute one list using the permutation of indices resulting from sorting the other list?

Answer 1

Schwartzian transform

list_1_sorted, list_2_sorted = zip(*sorted(zip(list_1, list_2),
  key=operator.itemgetter(0), reverse=True))
