For example, `dependency_c` can have a dependency on `dependency_b`, and `dependency_b` on `dependency_a`:

{* ../../docs_src/dependencies/tutorial008_an_py39.py hl[6,14,22] *}

And all of them can use `yield`.

In this case `dependency_c`, to execute its exit code, needs the value from `dependency_b` (here named `dep_b`) to still be available.

{* ../../docs_src/dependencies/tutorial008_an_py39.py hl[6,14,22] *}

이들 모두는 `yield`를 사용할 수 있습니다.

이 경우 `dependency_c`는 종료 코드를 실행하기 위해, `dependency_b`의 값 (여기서는 `dep_b`로 명명)이 여전히 사용 가능해야 합니다.

그리고, `dependency_b`는 종료 코드를 위해 `dependency_a`의 값 (여기서는 `dep_a`로 명명) 이 사용 가능해야 합니다.

## Number validations: greater than and less than or equal { #number-validations-greater-than-and-less-than-or-equal }

The same applies for:

* `gt`: `g`reater `t`han
* `le`: `l`ess than or `e`qual

{* ../../docs_src/path_params_numeric_validations/tutorial005_an_py39.py hl[10] *}

{* ../../docs_src/path_params_numeric_validations/tutorial003_an_py39.py hl[10] *}

## Validations numériques : supérieur ou égal

Avec `Query` et `Path` (et d'autres que vous verrez plus tard) vous pouvez déclarer des contraintes numériques.

Ici, avec `ge=1`, `item_id` devra être un nombre entier "`g`reater than or `e`qual" à `1`.

{* ../../docs_src/path_params_numeric_validations/tutorial004_an_py39.py hl[10] *}

{* ../../docs_src/path_params_numeric_validations/tutorial004_an_py39.py hl[10] *}

## Validações numéricas: maior que e menor que ou igual { #number-validations-greater-than-and-less-than-or-equal }

O mesmo se aplica a:

* `gt`: maior que (`g`reater `t`han)
* `le`: menor que ou igual (`l`ess than or `e`qual)

{* ../../docs_src/path_params_numeric_validations/tutorial005_an_py39.py hl[10] *}

{* ../../docs_src/path_params_numeric_validations/tutorial004_an_py39.py hl[10] *}

## Validaciones numéricas: mayor que y menor o igual { #number-validations-greater-than-and-less-than-or-equal }

Lo mismo aplica para:

* `gt`: `g`reater `t`han
* `le`: `l`ess than or `e`qual

{* ../../docs_src/path_params_numeric_validations/tutorial005_an_py39.py hl[10] *}

{* ../../docs_src/path_params_numeric_validations/tutorial004_an_py39.py hl[10] *}

## Validierung von Zahlen: Größer und kleiner oder gleich { #number-validations-greater-than-and-less-than-or-equal }

Das Gleiche gilt für:

* `gt`: `g`reater `t`han (größer als)
* `le`: `l`ess than or `e`qual (kleiner oder gleich)

{* ../../docs_src/path_params_numeric_validations/tutorial005_an_py39.py hl[10] *}

{* ../../docs_src/path_params_numeric_validations/tutorial004_an_py39.py hl[10] *}

## Валідація числових даних: більше ніж і менше або дорівнює

Те саме застосовується до:

* `gt`: `g`reater `t`han (більше ніж)
* `le`: `l`ess than or `e`qual (менше або дорівнює)

{* ../../docs_src/path_params_numeric_validations/tutorial005_an_py39.py hl[10] *}

## Валідація числових даних: float, більше ніж і менше ніж

{* ../../docs_src/path_params_numeric_validations/tutorial004_an_py39.py hl[10] *}

## Валидация числовых данных: больше и меньше или равно { #number-validations-greater-than-and-less-than-or-equal }

То же самое применимо к:

* `gt`: больше (`g`reater `t`han)
* `le`: меньше или равно (`l`ess than or `e`qual)

{* ../../docs_src/path_params_numeric_validations/tutorial005_an_py39.py hl[10] *}
