Örneğin, [bir dosyayı okumak için `with` kullanabilirsiniz](https://docs.python.org/3/tutorial/inputoutput.html#reading-and-writing-files):

```Python
with open("./somefile.txt") as f:
    contents = f.read()
    print(contents)
```

Temelde `open("./somefile.txt")`, "Context Manager" olarak adlandırılan bir nesne oluşturur.

`with` bloğu bittiğinde, exception olsa bile dosyanın kapatılmasını garanti eder.

user_dict = user_in.model_dump()
```

artık `user_dict` değişkeninde modelin verilerini içeren bir `dict` vardır (Pydantic model nesnesi yerine bir `dict` elde etmiş oluruz).

Ve eğer şunu çağırırsak:

```Python
print(user_dict)
```

şöyle bir Python `dict` elde ederiz:

```Python
{
    'username': 'john',
    'password': 'secret',
    'email': '******@****.***',
    'full_name': None,
}
```
