Do this:

>>> from ast import literal_eval
>>> 
>>> 
>>> literal_eval("[{'id': 453, 'name': 'Paulo'}]")
[{'id': 453, 'name': 'Paulo'}]

Why not just `eval`? – Federico klez Culloca Feb 21 '19 at 15:25

`eval` is okay, but usually it's safer to use literal eval. This is explained nicely [here](https://stackoverflow.com/a/34904657/5019169) – Ahsanul Haque Feb 21 '19 at 15:27
