Get indices of the top N values of a list

Question

I have a list say a = [5,3,1,4,10]. I need to get indices of the top two values of the list, that is for 5 and 10 I would get [0

Answer 1

Just a NumPy alternative:

import numpy as np

top_2_idx = np.argsort(a)[-2:]
top_2_values = [a[i] for i in top_2_idx]
