# ⭐️ A simple example ⭐️
```python
from pydwrap import BaseModel, Option
class User(BaseModel):
name: Option[str]
age: int
data = {
"age": 20
}
user = User(**data)
#> User(name=Option(None), age=20)
print("Hello", user.name.unwrap(error_msg="What's your name?") + "!")
#> ValueError: What's your name?
```
