## Zweite Abhängigkeit, „Dependable“ und „Dependant“ { #second-dependency-dependable-and-dependant }

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

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[13] *}

## Second dependency, "dependable" and "dependant" { #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):

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[13] *}

Let's focus on the parameters declared:

## İkinci bağımlılık: "dependable" ve "dependant" { #second-dependency-dependable-and-dependant }

Ardından, aynı zamanda kendi içinde bir bağımlılık da tanımlayan başka bir bağımlılık fonksiyonu (bir "dependable") oluşturabilirsiniz (yani o da bir "dependant" olur):

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[13] *}

## Друга залежність, «dependable» і «dependant» { #second-dependency-dependable-and-dependant }

Далі ви можете створити іншу функцію залежності («dependable»), яка водночас оголошує власну залежність (тож вона також є «dependant»):

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[13] *}

Зосередьмося на оголошених параметрах:

## Segunda dependencia, "dependable" y "dependant" { #second-dependency-dependable-and-dependant }

Luego puedes crear otra función de dependencia (un "dependable") que al mismo tiempo declare una dependencia propia (por lo que también es un "dependant"):

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[13] *}

Centrémonos en los parámetros declarados:

이것을 해결하는 일은 **FastAPI**가 알아서 처리합니다.

## 첫 번째 의존성 "dependable" { #first-dependency-dependable }

다음과 같이 첫 번째 의존성("dependable")을 만들 수 있습니다:

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[8:9] *}

이 의존성은 선택적 쿼리 파라미터 `q`를 `str`로 선언하고, 그대로 반환합니다.

매우 단순한 예시(그다지 유용하진 않음)이지만, 하위 의존성이 어떻게 동작하는지에 집중하는 데 도움이 됩니다.

## 두 번째 의존성 "dependable"과 "dependant" { #second-dependency-dependable-and-dependant }

它們可以按你的需要，層級任意加深。

**FastAPI** 會負責解析它們。

## 第一個相依項 "dependable" { #first-dependency-dependable }

你可以建立第一個相依項（"dependable"）如下：

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[8:9] *}

它宣告了一個可選的查詢參數 `q`（型別為 `str`），然後直接回傳它。

這很簡單（不太實用），但有助於我們專注於子相依如何運作。

## 第二個相依，同時是 "dependable" 也是 "dependant" { #second-dependency-dependable-and-dependant }

接著你可以建立另一個相依函式（"dependable"），同時它也宣告了自己的相依（因此它同時也是 "dependant"）：
