Lưu ý rằng, điều này có nghĩa rằng "`one_person`" là một **thực thể** của lớp `Person`.

Nó không có nghĩa "`one_person`" là một **lớp** gọi là `Person`.

Notice that this means "`one_person` is an **instance** of the class `Person`".

It doesn't mean "`one_person` is the **class** called `Person`".

## Pydantic models

<a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> is a Python library to perform data validation.

You declare the "shape" of the data as classes with attributes.

### Tip olarak Sınıflar

Bir değişkenin tipini bir sınıf ile bildirebilirsiniz.

Diyelim ki  `name` değerine sahip `Person` sınıfınız var:

```Python hl_lines="1-3"
{!../../../docs_src/python_types/tutorial010.py!}
```

Sonra bir değişkeni 'Person' tipinde tanımlayabilirsiniz:

```Python hl_lines="6"
{!../../../docs_src/python_types/tutorial010.py!}
```

### Класи як типи

Ви також можете оголосити клас як тип змінної.

Скажімо, у вас є клас `Person` з імʼям:

```Python hl_lines="1-3"
{!../../../docs_src/python_types/tutorial010.py!}
```

Потім ви можете оголосити змінну типу `Person`:

```Python hl_lines="6"
{!../../../docs_src/python_types/tutorial010.py!}
```

Here's how to help others with questions (in discussions or issues):

### Understand the question

* Check if you can understand what is the **purpose** and use case of the person asking.

* Then check if the question (the vast majority are questions) is **clear**.
