Python Convert str with list to list

Question

I have message which is a list and JSON in it. I managed to get JSON with raw decode. The problem is

string = "["a,b","b,c"]"

How can I convert that string into a list?

`json.decode` it again? For the record, that's not the string you have (the lack of escaped quotes/failure to use different quotes for inner/outer quotes means it's syntactically invalid as a string literal). — ShadowRanger, Sep 14 '22 at 11:05

Use ast.literal_eval:

import ast

print(ast.literal_eval(string))

Since this is JSON, use the json module:

import json

print(json.loads(string))

string = "['a,b','b,c']"

print(eval(string))

No! Don't use eval! This is unsafe! – pigrammer Sep 15 '22 at 21:14
Why/how does this work, and why is it dangerous in the context of the question? – greybeard Sep 18 '22 at 06:29
