## Validaciones numéricas: mayor o igual { #number-validations-greater-than-or-equal }

Con `Query` y `Path` (y otros que verás más adelante) puedes declarar restricciones numéricas.

Aquí, con `ge=1`, `item_id` necesitará ser un número entero "`g`reater than or `e`qual" a `1`.

{* ../../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)
