First, let's quickly see the parts that change from the examples in the main **Tutorial - User Guide** for [OAuth2 with Password (and hashing), Bearer with JWT tokens](../../tutorial/security/oauth2-jwt.md){.internal-link target=_blank}. Now using OAuth2 scopes:

{* ../../docs_src/security/tutorial005_an_py310.py hl[5,9,13,47,65,106,108:116,122:126,130:136,141,157] *}

Now let's review those changes step by step.

FastAPI는 0.95.0 버전부터 `Annotated`에 대한 지원을 (그리고 이를 사용하기 권장합니다) 추가했습니다.

옛날 버전을 가지고 있는 경우, `Annotated`를 사용하려 하면 에러를 맞이하게 될 것입니다.

`Annotated`를 사용하기 전에 최소 0.95.1로 [FastAPI 버전 업그레이드](../../deployment/versions.md#fastapi_2){.internal-link target=_blank}를 확실하게 하세요.

### `Depends` 불러오기

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[3] *}

### "의존자"에 의존성 명시하기

### 現代 Python

這一切都基於標準的 **Python 型別**宣告（感謝 Pydantic）。無需學習新的語法，只需使用標準的現代 Python。

如果你需要 2 分鐘來學習如何使用 Python 型別（即使你不使用 FastAPI），可以看看這個簡短的教學：[Python 型別](python-types.md){.internal-link target=_blank}。

如果你寫帶有 Python 型別的程式碼：

```python
from datetime import date

from pydantic import BaseModel

# 宣告一個變數為 string
# 並在函式中獲得 editor support
def main(user_id: str):

                        buf.append(content).append(' ');
                    } catch (final Exception e) {
                        if (logger.isDebugEnabled()) {
                            logger.debug("Exception in an internal extractor.", e);
                        }
                    }
                }
            }
        } catch (final MessagingException e) {
            if (logger.isDebugEnabled()) {
