features    map[string]bool              // set
	imported    map[string]*apiPackage       // packages already imported
	stdPackages []string                     // names, omitting "unsafe", internal, and vendored packages
	importMap   map[string]map[string]string // importer dir -> import path -> canonical path
	importDir   map[string]string            // canonical import path -> dir

}

Agora, vamos ver o módulo em `app/main.py`.

Aqui é onde você importa e usa a classe `FastAPI`.

Este será o arquivo principal em seu aplicativo que une tudo.

E como a maior parte de sua lógica agora viverá em seu próprio módulo específico, o arquivo principal será bem simples.

### Importe o `FastAPI` { #import-fastapi }

Você importa e cria uma classe `FastAPI` normalmente.

from app.routers import items, users
```

/// info | Información

La primera versión es un "import relativo":

```Python
from .routers import items, users
```

La segunda versión es un "import absoluto":

```Python
from app.routers import items, users
```

Wir könnten sie auch wie folgt importieren:

```Python
from app.routers import items, users
```

/// info | Info

Die erste Version ist ein „relativer Import“:

```Python
from .routers import items, users
```

Die zweite Version ist ein „absoluter Import“:

```Python
from app.routers import items, users
```

And then we do the same for the module `users`.

We could also import them like:

```Python
from app.routers import items, users
```

/// info

The first version is a "relative import":

```Python
from .routers import items, users
```

The second version is an "absolute import":

```Python
from app.routers import items, users
```
