Python list string to list

Question

I have a string:

s= \"[7, 9, 41, [32, 67]]\"

and I need to convert that string into a list:

l= [7, 9, 41, [32, 67]]
         


        

Answer 1

Use the ast module, it has a handy .literal_eval() function:

import ast

l = ast.literal_eval(s)

On the python prompt:

>>> import ast
>>> s= "[7, 9, 41, [32, 67]]"
>>> ast.literal_eval(s)
[7, 9, 41, [32, 67]]
