## Zweite Abhängigkeit, „Dependable“ und „Dependant“

Dann können Sie eine weitere Abhängigkeitsfunktion (ein „Dependable“) erstellen, die gleichzeitig eine eigene Abhängigkeit deklariert (also auch ein „Dependant“ ist):

=== "Python 3.10+"

    ```Python hl_lines="13"
    {!> ../../../docs_src/dependencies/tutorial005_an_py310.py!}
    ```

class SecurityRequirement:
    def __init__(
        self, security_scheme: SecurityBase, scopes: Optional[Sequence[str]] = None
    ):
        self.security_scheme = security_scheme
        self.scopes = scopes


class Dependant:
    def __init__(
        self,
        *,
        path_params: Optional[List[ModelField]] = None,
        query_params: Optional[List[ModelField]] = None,
        header_params: Optional[List[ModelField]] = None,

This is quite simple (not very useful), but will help us focus on how the sub-dependencies work.

## Second dependency, "dependable" and "dependant"

Then you can create another dependency function (a "dependable") that at the same time declares a dependency of its own (so it is a "dependant" too):

=== "Python 3.10+"

    ```Python hl_lines="13"
    {!> ../../../docs_src/dependencies/tutorial005_an_py310.py!}
    ```

    !!! tip
        Prefer to use the `Annotated` version if possible.

    ```Python hl_lines="3"
    {!> ../../../docs_src/dependencies/tutorial001.py!}
    ```

### Declare the dependency, in the "dependant"

The same way you use `Body`, `Query`, etc. with your *path operation function* parameters, use `Depends` with a new parameter:

=== "Python 3.10+"

    ```Python hl_lines="13  18"

                    } else {
                        out[j++] = ch;
                    }
                    break;
                case 1:
                    /* Get ASCII hex value and convert to platform dependant
                     * encoding like EBCDIC perhaps
                     */
                    b[0] = (byte)(Integer.parseInt( str.substring( i, i + 2 ), 16 ) & 0xFF);

     * address, isPermanent, isBeingDeleted, ...etc. This information can only
     * be retrieved with the Node Status request.
     * 
     * The degree of state that an NbtAddress has is dependant on how it was
     * created and what is required of it. The second degree of state is the
     * most common. This is the state information that would be retrieved from
