## Qué hace a una dependencia

Hasta ahora has visto dependencias declaradas como funciones.

Pero esa no es la única forma de declarar dependencias (aunque probablemente sea la más común).

El factor clave es que una dependencia debe ser un "callable".

Un "**callable**" en Python es cualquier cosa que Python pueda "llamar" como una función.

  <description>Maven 4 API - CLI.</description>

  <dependencies>
    <dependency>
      <groupId>org.apache.maven</groupId>
      <artifactId>maven-api-annotations</artifactId>
    </dependency>
    <dependency>
      <groupId>org.apache.maven</groupId>
      <artifactId>maven-api-core</artifactId>
    </dependency>
    <dependency>
      <groupId>org.apache.maven</groupId>
      <artifactId>maven-api-xml</artifactId>

And then **FastAPI** will call that override instead of the original dependency.

{* ../../docs_src/dependency_testing/tutorial001_an_py310.py hl[26:27,30] *}

/// tip

You can set a dependency override for a dependency used anywhere in your **FastAPI** application.
