**Nota**: Asegúrate de poner `"fastapi[standard]"` entre comillas para asegurar que funcione en todas las terminales.

## Ejemplo { #example }

### Créalo { #create-it }

Crea un archivo `main.py` con:

```Python
from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")

</div>

**Nota**: Certifique-se de que você colocou `"fastapi[standard]"` com aspas, para garantir que funcione em todos os terminais.

## Exemplo { #example }

### Crie { #create-it }

Crie um arquivo `main.py` com:

```Python
from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")

2. **Commits**:
   - Write clear messages: what changed and why (e.g., “Refactor S3 API handler to reduce latency so that requests process 20% faster”).
   - Rebase to tidy commits before submitting (e.g., `git rebase -i main` to squash typos or reword messages), unless multiple contributors worked on the branch.
   - Keep PRs focused—one feature or fix. Split large changes into multiple PRs.

3. **Testing**:

    //                                                                      Search Execute
    //                                                                      ==============

    @Execute
    @Secured({ ROLE, ROLE + VIEW })
    public HtmlResponse index() {
        saveToken();

    }

    @Test
    public void test_suppressedExceptions() {
        // Test suppressed exceptions functionality
        ResultOffsetExceededException mainException = new ResultOffsetExceededException("Main exception");
        ResultOffsetExceededException suppressedException = new ResultOffsetExceededException("Suppressed exception");

        mainException.addSuppressed(suppressedException);
