I try to evaluate some Python expressions like `[1, 2, 3][1]`. I can't use `eval('[1, 2, 3][1]')` because every time I do that, a kitten might die. A safer way is to use `ast.literal_eval('[1, 2, 3][1]')`, however, it raises a ValueError:

```
ValueError: malformed node or string ...

```

What can be done in order to make it work? Thanks in advance.
