```Python
some_variable: PlaneItem | CarItem
```

But if we put that in the assignment `response_model=PlaneItem | CarItem` we would get an error, because Python would try to perform an **invalid operation** between `PlaneItem` and `CarItem` instead of interpreting that as a type annotation.

## List of models { #list-of-models }

The same way, you can declare responses of lists of objects.

            // To test this properly, we would need to mock connect0() and the tree object.
