Estamos importando o submódulo `items` diretamente, em vez de importar apenas sua variável `router`.

Isso ocorre porque também temos outra variável chamada `router` no submódulo `users`.

Se tivéssemos importado um após o outro, como:

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

o `router` de `users` sobrescreveria o de `items` e não poderíamos usá-los ao mesmo tempo.

## Import `Field` { #import-field }

First, you have to import it:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[4] *}


/// warning

Notice that `Field` is imported directly from `pydantic`, not from `fastapi` as are all the rest (`Query`, `Path`, `Body`, etc).

///

## Declare model attributes { #declare-model-attributes }

You can then use `Field` with model attributes:

    }

    public Map<Object, InputLocation> getLocations() {
        return locations;
    }

    /**
     * Gets the parent InputLocation where this InputLocation may have been imported from.
     * Can return {@code null}.
     *
     * @return InputLocation
     * @since 4.0.0
     */
    @Override
    public InputLocation getImportedFrom() {
        return importedFrom;
    }

So, the section:

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

will run.

---

This won't happen if you import that module (file).

So, if you have another file `importer.py` with:

```Python
from myapp import app

# Some more code
```

in that case, the automatically created variable inside of `myapp.py` will not have the variable `__name__` with a value of `"__main__"`.

    this.keyTable = keyTable;
    this.valueTable = valueTable;
    this.entries = entries;
    this.mask = mask;
    this.hashCode = hashCode;
  }

  // checkNoConflictInKeyBucket is static imported from RegularImmutableMap

  /**
   * @throws IllegalArgumentException if another entry in the bucket has the same key
   * @throws BucketOverflowException if this bucket has too many entries, which may indicate a hash

## Technical Details { #technical-details }

The class `BackgroundTasks` comes directly from <a href="https://www.starlette.io/background/" class="external-link" target="_blank">`starlette.background`</a>.

It is imported/included directly into FastAPI so that you can import it from `fastapi` and avoid accidentally importing the alternative `BackgroundTask` (without the `s` at the end) from `starlette.background`.

E seus usuários poderiam fazer login tanto pela sua aplicação Django quanto pela sua aplicação **FastAPI**, ao mesmo tempo.

## Criar o hash e verificar as senhas

Importe as ferramentas que nós precisamos de `passlib`.

Crie um "contexto" do PassLib. Este será usado para criar o hash e verificar as senhas.
