It is just a function that can take all the same parameters that a *path operation function* can take:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[8:9] *}

That's it.

**2 lines**.

And it has the same shape and structure that all your *path operation functions* have.

You can think of it as a *path operation function* without the "decorator" (without the `@app.get("/some-path")`).

`FastAPI` es una clase que hereda directamente de `Starlette`.

También puedes usar toda la funcionalidad de <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a>.

### Paso 2: crea un "instance" de `FastAPI`

```Python hl_lines="3"
{!../../docs_src/first_steps/tutorial001.py!}
```

Aquí la variable `app` será un instance de la clase `FastAPI`.

Vous pouvez donc aussi utiliser toutes les fonctionnalités de <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a> depuis `FastAPI`.

### Étape 2 : créer une "instance" `FastAPI`

```Python hl_lines="3"
{!../../docs_src/first_steps/tutorial001.py!}
```

Ici la variable `app` sera une "instance" de la classe `FastAPI`.

Você pode usar todas as funcionalidades do <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a> com `FastAPI` também.

### Passo 2: crie uma "instância" de `FastAPI`

```Python hl_lines="3"
{!../../docs_src/first_steps/tutorial001.py!}
```

Aqui, a variável `app` será uma "instância" da classe `FastAPI`.

		case *map[string]interface{}:
			(*values)[pkFieldName] = insertID
