## Detalles Técnicos

Las versiones modernas de Python tienen soporte para **"código asíncrono"** usando algo llamado **"coroutines"**, usando la sintaxis **`async` y `await`**.

Veamos esa frase por partes en las secciones siguientes:

* **Código Asíncrono**
* **`async` y `await`**
* **Coroutines**
