* When translating a document, do not "pre-translate" `#hash-parts` that link to headings in untranslated documents.

## Tests

There is a script that you can run locally to test all the code and generate coverage reports in HTML:

<div class="termy">

```console
$ bash scripts/test-cov-html.sh
```

</div>

We are importing the submodule `items` directly, instead of importing just its variable `router`.

This is because we also have another variable named `router` in the submodule `users`.

If we had imported one after the other, like:

```Python
from .routers.items import router
from .routers.users import router
```

    ```Python hl_lines="1"
    {!> ../../../docs_src/python_types/tutorial006.py!}
    ```

    Declare the variable, with the same colon (`:`) syntax.

    As the type, put the `List` that you imported from `typing`.

    As the list is a type that contains some internal types, you put them in square brackets:

    ```Python hl_lines="4"
    {!> ../../../docs_src/python_types/tutorial006.py!}
    ```

## Tests

Es gibt ein Skript, das Sie lokal ausführen können, um den gesamten Code zu testen und Code Coverage Reporte in HTML zu generieren:

<div class="termy">

```console
$ bash scripts/test-cov-html.sh
```

</div>

We also declare a special parameter of type `SecurityScopes`, imported from `fastapi.security`.

This `SecurityScopes` class is similar to `Request` (`Request` was used to get the request object directly).

=== "Python 3.10+"

    ```Python hl_lines="8  105"

We name it `SessionLocal` to distinguish it from the `Session` we are importing from SQLAlchemy.

We will use `Session` (the one imported from SQLAlchemy) later.

To create the `SessionLocal` class, use the function `sessionmaker`:

```Python hl_lines="11"
{!../../../docs_src/sql_databases/sql_app/database.py!}
```
