I have a list written in a string how I can turn it into a real list in Python

Question

I have a list written in a string how I can turn it into a real list in Python example:

list 1 = "[[1,2],
           [3,4]]"

thank you

Answer 1

Use ast.literal_eval to safely evaluate the list

list_1 = "[[1,2], [3,4]]"
l=ast.literal_eval(list_1)
