Still, in both situations, chances are that **FastAPI** will [still be faster](index.md#performance){.internal-link target=_blank} than (or at least comparable to) your previous framework.

## Установка FastAPI { #install-fastapi }

Первый шаг — установить FastAPI.

Убедитесь, что вы создали [виртуальное окружение](../virtual-environments.md){.internal-link target=_blank}, активировали его, и затем **установите FastAPI**:

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

## FastAPI installieren { #install-fastapi }

Der erste Schritt besteht darin, FastAPI zu installieren.

Stellen Sie sicher, dass Sie eine [virtuelle Umgebung](../virtual-environments.md){.internal-link target=_blank} erstellen, sie aktivieren und dann **FastAPI installieren**:

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

/// info | 정보

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.

### 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):
