Pueden declarar requisitos de request (como headers) u otras sub-dependencias:

{* ../../docs_src/dependencies/tutorial006_an_py39.py hl[8,13] *}

### Lanzar excepciones { #raise-exceptions }

Estas dependencias pueden `raise` excepciones, igual que las dependencias normales:

{* ../../docs_src/dependencies/tutorial006_an_py39.py hl[10,15] *}

### Valores de retorno { #return-values }

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

## 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/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)
