How to convert a list in string form to a list

Question

Suppose a string s="[1,2,3]"

I want the list to be l=[1,2,3], where type(l) is list

How can I achieve this

Have a look at [`ast.literal_eval`](https://docs.python.org/2/library/ast.html#ast.literal_eval) (and don't use [`eval`](https://docs.python.org/2/library/functions.html#eval)) — khelwood, Nov 24 '16 at 10:00

Try this ,

In [3]:  l = eval(s)

In [4]: print l
[1, 2, 3]

You shouldn't suggest [very dangerous functions like `eval`](http://nedbatchelder.com/blog/201206/eval_really_is_dangerous.html) when there are better options. – Matthias Nov 24 '16 at 10:20

import json

s="[1,2,3]"
s_list = json.loads(s)
print(type(s_list))

out:

<type 'list'>
