Inconsistency in spelling conventions can lead to several issues:

* **Confusion for users and contributors**: Mixed spellings (e.g., "color" and "colour", "initialize" and "initialise") in the codebase create confusion about which variant to use

Using these `dependencies` in the *path operation decorator* you can make sure they are executed while avoiding editor/tooling errors.

It might also help avoid confusion for new developers that see an unused parameter in your code and could think it's unnecessary.

In this example we use invented custom headers `X-Key` and `X-Token`.

 * <p>Repository validation ensures data integrity by:

 *   <li>Preventing duplicate repositories that could cause confusion</li>
 *   <li>Rejecting null repository entries that would cause failures</li>
 *   <li>Maintaining consistent repository ordering for reproducible builds</li>

With this you should have a basic understanding of what **environment variables** are and how to use them in Python.

Usando estas `dependencies` en el decorador de *path operation* puedes asegurarte de que se ejecutan mientras evitas errores en editores/herramientas.

También puede ayudar a evitar confusiones para nuevos desarrolladores que vean un parámetro no usado en tu código y puedan pensar que es innecesario.
