# Security Tools

When you need to declare dependencies with OAuth2 scopes you use `Security()`.

But you still need to define what is the dependable, the callable that you pass as a parameter to `Depends()` or `Security()`.

There are multiple tools that you can use to create those dependables, and they get integrated into OpenAPI so they are shown in the automatic docs UI, they can be used by automatically generated clients and SDKs, etc.

Im vorherigen Beispiel haben wir ein <abbr title="Dictionary – Zuordnungstabelle: In anderen Sprachen auch Hash, Map, Objekt, Assoziatives Array genannt">`dict`</abbr> von unserer Abhängigkeit („Dependable“) zurückgegeben:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[9] *}

Aber dann haben wir ein `dict` im Parameter `commons` der *Pfadoperation-Funktion*.

* Cross-Origin Resource Sharing: Cross-Origin Resource Sharing (do not translate to "Compartilhamento de Recursos de Origem Cruzada")
* Deep Learning: Deep Learning (do not translate to "Aprendizado Profundo")
* dependable: dependable
* dependencies: dependências

이 모든 사항을 할 때 코드 반복을 최소화합니다.

## 첫번째 단계 { #first-steps }

아주 간단한 예제를 봅시다. 너무 간단할 것이기에 지금 당장은 유용하지 않을 수 있습니다.

하지만 이를 통해 **의존성 주입** 시스템이 어떻게 작동하는지에 중점을 둘 것입니다.

### 의존성 혹은 "디펜더블" 만들기 { #create-a-dependency-or-dependable }

의존성에 집중해 봅시다.

*경로 처리 함수*가 가질 수 있는 모든 매개변수를 갖는 단순한 함수입니다:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[8:9] *}

이게 다입니다.

**단 두 줄입니다**.
