print(map(int, "[1,2,3]".replace('[', '').replace(']', '').split(',')))

We remove the "[" and "]"
We do split() for the , to get a list
We only need to convert each element in a int , we do it with map(lista, int)

I already managed to find 2 alternatives:

first:

valor_inicial = str([1,2,3])

import json
json.loads(valor_inicial)

second:

from ast import literal_eval

valor_inicial = str([1,2,3])
literal_eval(valor_inicial)
