Python - String to list

Question

I need cast a list to a string and get back the string to a list. There\'s a python way to make this behavior?

l1 = [\'aa\',\'bb\',\'cc\']
s = str(l1)
l2 = c         


        

Answer 1

You can use ast module:

import ast

l1 = ['aa','bb','cc']
s = str(l1)
ast.literal_eval(s)
>>> ['aa','bb','cc']

Or something like this - but i don't like it too much:

l1 = ['aa','bb','cc']
s = str(l1)
l2 = [x.strip(" '") for x in s.strip('[]').split(',')]
