[Tutor] Original indices after Sorting

[Ali Torkamani]

By the way, I myself, have this solution:

How can we get the indices of values in the original list after sorting a

(Pdb) A=[ 1, -1, 0, 7, 9, 1.3, 2.9 ]
(Pdb) sorted(zip(A, range(len(A))), key = lambda x: x[0])
[(-1, 1), (0, 2), (1, 0), (1.3, 5), (2.9, 6), (7, 3), (9, 4)]


But compared to what Matlab neatly does, it's too ugly:

A
