Vous remarquerez que pour créer une instance d'une classe Python, vous utilisez la même syntaxe.

Par exemple :

```Python
class Cat:
    def __init__(self, name: str):
        self.name = name


fluffy = Cat(name="Mr Fluffy")
```

Dans ce cas, `fluffy` est une instance de la classe `Cat`.

Et pour créer `fluffy`, vous « appelez » `Cat`.

Python'da bir class'tan instance oluştururken de aynı söz dizimini kullandığınızı fark etmiş olabilirsiniz.

Örneğin:

```Python
class Cat:
    def __init__(self, name: str):
        self.name = name


fluffy = Cat(name="Mr Fluffy")
```

Bu durumda `fluffy`, `Cat` class'ının bir instance'ıdır.

Ve `fluffy` oluşturmak için `Cat`'i "çağırmış" olursunuz.
