The question is not about an empty list like this one
e.g. I have an object which could be either list or None
I find a way to create a list from it like

maybe_list = _get_list_or_none()
maybe_list = maybe_list if maybe_list else []

Maybe you can help me to find a more natural and idiomatic way to do it

`definitely_list = _get_list_or_none() or []`…?! – deceze Feb 19 '20 at 09:00

you can check type, you will get answer list or none – Mohit Sharma Feb 19 '20 at 09:00

the idiomatic way to check if something is `None` is `if some_object is None`, but your approach already works, and is decently idiomatic – juanpa.arrivillaga Feb 19 '20 at 09:00
