Solo tocamos los conceptos básicos, pero ya te haces una idea de cómo funciona todo.

Intenta cambiar la línea con:

```Python
    return {"item_name": item.name, "item_id": item_id}
```

...desde:

```Python
        ... "item_name": item.name ...
```

...a:

```Python
        ... "item_price": item.price ...
```

Nós apenas arranhamos a superfície, mas você já tem idéia de como tudo funciona.

Experimente mudar a seguinte linha:

```Python
    return {"item_name": item.name, "item_id": item_id}
```

...de:

```Python
        ... "item_name": item.name ...
```

...para:

```Python
        ... "item_price": item.price ...
```

Tham số `name` được định nghĩa là `Optional[str]`, nhưng nó **không phải là tùy chọn**, bạn không thể gọi hàm mà không có tham số:

```Python
say_hi()  # Oh, no, this throws an error! 😱
```

Tham số `name` **vẫn được yêu cầu** (không phải là *tùy chọn*) vì nó không có giá trị mặc định. Trong khi đó, `name` chấp nhận `None` như là giá trị:

```Python
say_hi(name=None)  # This works, None is valid 🎉
```

    public String url;

    /** Minimum error count filter */
    public Integer errorCountMin;

    /** Maximum error count filter */
    public Integer errorCountMax;

    /** Name or type of the error */
    public String errorName;

{% endfor %}
{% endfor %}

[Prometheus](https://prometheus.io) is a cloud-native monitoring platform. Prometheus offers a multi-dimensional data model with time series data identified by metric name and key/value pairs. The data collection happens via a pull model over HTTP/HTTPS. Users looking to monitor their MinIO instances can point Prometheus configuration to scrape data from following endpoints.
