## Install FastAPI

The first step is to install FastAPI.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then **install FastAPI**:

<div class="termy">

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

---> 100%
```

</div>

# 벤치마크

독립적인 TechEmpower 벤치마크에 따르면 **FastAPI** 애플리케이션이 Uvicorn을 사용하여 <a href="https://www.techempower.com/benchmarks/#section=test&runid=7464e520-0dc2-473d-bd34-dbdfd7e85911&hw=ph&test=query&l=zijzen-7" class="external-link" target="_blank">가장 빠른 Python 프레임워크 중 하나</a>로 실행되며, Starlette와 Uvicorn 자체(내부적으로 FastAPI가 사용하는 도구)보다 조금 아래에 위치합니다.

그러나 벤치마크와 비교를 확인할 때 다음 사항을 염두에 두어야 합니다.

## 벤치마크와 속도

벤치마크를 확인할 때, 일반적으로 여러 가지 유형의 도구가 동등한 것으로 비교되는 것을 볼 수 있습니다.

描述内容比较长且占用多行时，可以在函数的 <abbr title="函数中作为第一个表达式，用于文档目的的一个多行字符串（并没有被分配个任何变量）">docstring</abbr> 中声明*路径操作*的描述，**FastAPI** 支持从文档字符串中读取描述内容。

文档字符串支持 <a href="https://en.wikipedia.org/wiki/Markdown" class="external-link" target="_blank">Markdown</a>，能正确解析和显示 Markdown 的内容，但要注意文档字符串的缩进。

```Python hl_lines="19-27"

```
