How can I convert in Python 3.x string like this: {str} '[21,2,14]' into int array like this: {list: 3} [21,2,14] ?

    you can use ``json``, you can use ``ast``, or you can write your own parser – Mike Scotty Feb 12 '21 at 14:35

Use ast.literal_eval, a safer alternative to eval:

import ast
print(ast.literal_eval('[21,2,14]'))
# [21, 2, 14]

I like ast for tasks like this - https://docs.python.org/3/library/ast.html

import ast 
input_values = '[21,2,14]'
eval_input = ast.literal_eval(input_values)

outputs [21, 2, 14]
