(Pydantic 덕분에) FastAPI는 표준 **파이썬 3.6 타입** 선언에 기반하고 있습니다. 새로 배울 문법이 없습니다. 그저 표준적인 현대 파이썬입니다.

만약 여러분이 파이썬 타입을 어떻게 사용하는지에 대한 2분 정도의 복습이 필요하다면 (비록 여러분이 FastAPI를 사용하지 않는다 하더라도), 다음의 짧은 자습서를 확인하세요: [파이썬 타입](python-types.md){.internal-link target=\_blank}.

여러분은 타입을 이용한 표준 파이썬을 다음과 같이 적을 수 있습니다:

```Python
from datetime import date

from pydantic import BaseModel

# 변수를 str로 선언
# 그 후 함수 안에서 편집기 지원을 받으세요
def main(user_id: str):

   *
   * <p><b>Warning:</b> If the input future does not already implement {@code ListenableFuture}, the
   * returned future will emulate {@link ListenableFuture#addListener} by taking a thread from an
   * internal, unbounded pool at the first call to {@code addListener} and holding it until the
   * future is {@linkplain Future#isDone() done}.
   *
   * <p>Prefer to create {@code ListenableFuture} instances with {@link SettableFuture}, {@link

/// tip

You could also use `Enum`s the same way as with [Path Parameters](path-params.md#predefined-values){.internal-link target=_blank}.
