It means that **FastAPI** was specifically tested with the editors used by 80% of the Python developers. And as most of the other editors tend to work similarly, all its benefits should work for virtually all editors.

#### OpenAPI의 용도 { #what-is-openapi-for }

OpenAPI 스키마는 포함된 두 개의 대화형 문서 시스템을 제공합니다.

그리고 OpenAPI의 모든 것을 기반으로 하는 수십 가지 대안이 있습니다. **FastAPI**로 빌드한 애플리케이션에 이러한 대안을 쉽게 추가 할 수 있습니다.

这将会从 [PyPI](https://pypi.org/project/fastapi/) 下载一个压缩文件，其中包含 FastAPI 代码。

它还会**下载** FastAPI 依赖的其他软件包的文件。

然后它会**解压**所有这些文件，并将它们放在你的计算机上的一个目录中。

默认情况下，它会将下载并解压的这些文件放在随 Python 安装的目录中，这就是**全局环境**。

## 什么是虚拟环境 { #what-are-virtual-environments }

解决软件包都安装在全局环境中的问题的方法是为你所做的每个工程使用一个**虚拟环境**。

虚拟环境是一个**目录**，与全局环境非常相似，你可以在其中专为某个工程安装软件包。

这样，每个工程都会有自己的虚拟环境（`.venv` 目录），其中包含自己的软件包。

// Even if Read returns n < len(p), it may use all of p as scratch space during the call.
// If some data is available but not len(p) bytes, Read conventionally returns what is available instead of waiting for more.
// When Read encounters an error or end-of-file condition after successfully reading n > 0 bytes, it returns the number of bytes read.
