## Crie um ambiente virtual { #create-a-virtual-environment }

Ao começar a trabalhar em um projeto Python **pela primeira vez**, crie um ambiente virtual **<dfn title="existem outras opções, esta é uma diretriz simples">dentro do seu projeto</dfn>**.

/// tip | Dica

Você só precisa fazer isso **uma vez por projeto**, não toda vez que trabalhar.

## 与 OpenAPI 集成 { #integrated-with-openapi }

依赖项及子依赖项中声明的所有请求、验证和需求都会集成到同一个 OpenAPI 模式中。

因此，交互式文档中也会包含这些依赖项的所有信息：

<img src="/img/tutorial/dependencies/image01.png">

## 简单用法 { #simple-usage }

观察一下就会发现，只要*路径*和*操作*匹配，就会使用声明的*路径操作函数*。随后，**FastAPI** 会用正确的参数调用该函数，并从请求中提取数据。

事实上，所有（或大多数）Web 框架的工作方式都是这样的。

你从不会直接调用这些函数。它们由你的框架（此处为 **FastAPI**）调用。
