Tenha em mente que neste caso, o FastAPI não irá validar os conteúdos da lista.

Por exemplo, um `List[int]` iria validar (e documentar) que os contéudos da lista são números inteiros. Mas apenas `list` não.

from pydantic import BaseModel

# Declare a variable as a str
# and get editor support inside the function
def main(user_id: str):
    return user_id


# A Pydantic model
class User(BaseModel):
    id: int
    name: str
    joined: date
```

これは以下のように用いられます:

```Python
my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {
    "id": 4,
    "name": "Mary",
