Convert string with a list syntax to a list object

import ast


def get_list_from_string(input_lst_string: str) -> list:
    """
    Applies `ast.literal_eval` helper to `convert` input string to a list, and checks if the resulting object is a list
    indeed. If the string contains other Python's literal, like integer, ast.literal_eval will return it,
    as it is designed to parse any literals.

    As ast.literal_eval can be considered relatively safe from attacks, when with a string some executable code
    is passed, as function `understands` literals only (i.e., not a functions, classes, calls, operators). But,
    according to docs, it is not free from, say, potential memory exhaustion or stack exhaustion:
    https://docs.python.org/3/library/ast.html#ast.literal_eval

    :return: outpu_list - list parsed from string
