Up to now you have seen dependencies declared as functions.

But that's not the only way to declare dependencies (although it would probably be the more common).

The key factor is that a dependency should be a "callable".

A "**callable**" in Python is anything that Python can "call" like a function.

## Qué hace a una dependencia { #what-makes-a-dependency }

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.
