Substitution of list/dictionary element by the index in Hy

Question

Is there any way to substitute a value for an element of list or dictionary by the index in Hy? The nth function seems not corresponds to Python's square bracket.

I had expected like the following translation.

(setv lst [1 2 3])
(setv (nth lst 1) 20)

lst=[1, 2, 3]
lst[1]=20

Answer 1

According to the documentation, you have to use the assoc function to set a value at a specific index in a list. As such, your code should be:

(assoc lst 1 20)

This should give the desired result.
