Python | Índice de retorno de una lista ordenada

Ordene una lista en python y luego devuelva el índice de elementos en orden ordenado.

Ejemplos:

Input  : [2, 3, 1, 4, 5] 
Output : [2, 0, 1, 3, 4]
After sorting list becomes [1, 2, 3, 4, 5] 
and their index as [2, 0, 1, 3, 4]

Input  : [6, 4, 7, 8, 1]
Output : [4, 1, 0, 2, 3]
After sorting the list becomes [1, 4, 6, 7, 8] 
and their index as [4, 1, 0, 2, 3].

Método 1

import numpy
s = numpy.array([2, 3, 1, 4, 5])
sort_index = numpy.argsort(s)
print(sort_index)

Producción :

[2, 0, 1, 3, 4]

Método 2

s = [2, 3, 1, 4, 5]
li=[]
  
for i in range(len(s)):
      li.append([s[i],i])
li.sort()
sort_index = []
  
for x in li:
      sort_index.append(x[1])
  
print(sort_index)

Producción:

[2, 0, 1, 3, 4]
