```Python
user_dict = user_in.model_dump()
```

we now have a `dict` with the data in the variable `user_dict` (it's a `dict` instead of a Pydantic model object).

And if we call:

```Python
print(user_dict)
```

we would get a Python `dict` with:

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

For example you could have a file `main.py` with:

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

/// tip

The second argument to [`os.getenv()`](https://docs.python.org/3.8/library/os.html#os.getenv) is the default value to return.

Par exemple, vous pouvez avoir un fichier `main.py` contenant :

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

/// tip | Astuce

Le deuxième argument de [`os.getenv()`](https://docs.python.org/3.8/library/os.html#os.getenv) est la valeur par défaut à retourner.

```Python
user_dict = user_in.model_dump()
```

ahora tenemos un `dict` con los datos en la variable `user_dict` (es un `dict` en lugar de un objeto modelo Pydantic).

Y si llamamos a:

```Python
print(user_dict)
```

obtendríamos un `dict` de Python con:

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

Örneğin `main.py` adında bir dosyanız şöyle olabilir:

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

[`os.getenv()`](https://docs.python.org/3.8/library/os.html#os.getenv) fonksiyonunun ikinci argümanı, bulunamadığında döndürülecek varsayılan (default) değerdir.

        System.err.println("PR head: " + prHead);
        System.err.println("Base: " + baseSha);

        // One SHA per line to stdout so callers can pipe safely.
        System.out.print(stdout("git", "rev-list", baseSha + ".." + prHead));
    }

    private static boolean refExists(String ref) throws IOException, InterruptedException {
        ExecResult r = exec("git", "rev-parse", "--verify", ref);

             * for whatever reason. I copy over the uid here so it appears correct

            andx.uid = uid;

Например, у вас есть файл `main.py`:

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

Второй аргумент [`os.getenv()`](https://docs.python.org/3.8/library/os.html#os.getenv) - это возвращаемое по умолчанию значение.
