# 虛擬環境

當你在 Python 專案中工作時，你可能會需要使用一個**虛擬環境**（或類似的機制）來隔離你為每個專案安裝的套件。

/// info

如果你已經了解虛擬環境，知道如何建立和使用它們，你可以考慮跳過這一部分。🤓

///

/// tip

**虛擬環境**和**環境變數**是不同的。

**環境變數**是系統中的一個變數，可以被程式使用。

**虛擬環境**是一個包含一些檔案的目錄。

///

/// info

這個頁面將教你如何使用**虛擬環境**以及了解它們的工作原理。

如果你計畫使用一個**可以為你管理一切的工具**（包括安裝 Python），試試 <a href="https://github.com/astral-sh/uv" class="external-link" target="_blank">uv</a>。

`**second_user_data` quer dizer:

Passe as chaves e valores do dicionário `second_user_data` diretamente como argumentos chave-valor, equivalente a: `User(id=4, name="Mary", joined="2018-11-30")`

### Crear el Código de **FastAPI**

* Crea un directorio `app` y entra en él.

     *       module path, but is also compatible with placement on the class path. Compatibility can
     *       be achieved, for example, by repeating in the {@code META-INF/services/} directory the services
     *       that are declared in the {@code module-info.class} file. In that case, the path type can be chosen
     *       by the plugin.</li>
