## Repaso

* Importa `FastAPI`.
* Crea un instance de `app`.
* Escribe un **decorador de operación de path** (como `@app.get("/")`).
* Escribe una **función de la operación de path** (como `def root(): ...` arriba).

Dessa forma, ao digitar `python` no terminal, o sistema encontrará o programa Python em `/opt/custompython/bin` (último diretório) e o utilizará.

Digamos que você instala o Python e ele acaba em um diretório `C:\opt\custompython\bin`.

Se você disser sim para atualizar a variável de ambiente `PATH`, o instalador adicionará `C:\opt\custompython\bin` à variável de ambiente `PATH`.

Ya no pasará que escribas los nombres de key equivocados, o que tengas que revisar constantemente la documentación o desplazarte arriba y abajo para saber si usaste `username` o `user_name`.

### Corto

"                <img src=\"https://fast.wistia.com/embed/medias/$2/swatch\" style=\"filter:blur(5px);height:100%;object-fit:contain;width:100%;\" alt=\"$1\" aria-hidden=\"true\" onload=\"this.parentNode.style.opacity=1;\" /> \n" +
"        </div></div></div></div> \n" +
"    </div> \n" +
"  </div> \n" +
"</details>");


        document.body().html(rewritten);

this._element.parentNode.nodeType !== Node.ELEMENT_NODE) {\n      // Don't move modal's DOM position\n      document.body.appendChild(this._element)\n    }\n\n    this._element.style.display = 'block'\n    this._element.removeAttribute('aria-hidden')\n    this._element.setAttribute('aria-modal', true)\n    this._element.setAttribute('role', 'dialog')\n\n    if ($(this._dialog).hasClass(CLASS_NAME_SCROLLABLE) && modalBody) {\n      modalBody.scrollTop = 0\n    } else {\n      this._element.scrollTop = 0\n    }\n\n...

def update_item(item_id: int, item: Item):
    return {"item_name": item.name, "item_id": item_id}
```

El servidor debería recargar automáticamente (porque añadiste `--reload` al comando `uvicorn` que está más arriba).
