### Importar el `APIRouter` { #import-the-apirouter }

Ahora importamos los otros submódulos que tienen `APIRouter`s:

{* ../../docs_src/bigger_applications/app_an_py310/main.py hl[4:5] title["app/main.py"] *}

Como los archivos `app/routers/users.py` y `app/routers/items.py` son submódulos que son parte del mismo paquete de Python `app`, podemos usar un solo punto `.` para importarlos usando "imports relativos".

### Importe o `APIRouter` { #import-the-apirouter }

Agora importamos os outros submódulos que possuem `APIRouter`s:

{* ../../docs_src/bigger_applications/app_an_py310/main.py hl[4:5] title["app/main.py"] *}

Como os arquivos `app/routers/users.py` e `app/routers/items.py` são submódulos que fazem parte do mesmo pacote Python `app`, podemos usar um único ponto `.` para importá-los usando "importações relativas".

### Den `APIRouter` importieren { #import-the-apirouter }

Jetzt importieren wir die anderen Submodule, die `APIRouter` haben:

{* ../../docs_src/bigger_applications/app_an_py310/main.py hl[4:5] title["app/main.py"] *}

	fh.UncompressedSize64 = uint64(w.rawCount.count)

	if fh.isZip64() {
		fh.CompressedSize = uint32max
		fh.UncompressedSize = uint32max
		fh.ReaderVersion = zipVersion45 // requires 4.5 - File uses ZIP64 format extensions
	} else {
		fh.CompressedSize = uint32(fh.CompressedSize64)
		fh.UncompressedSize = uint32(fh.UncompressedSize64)
	}

	return w.writeDataDescriptor()
}

### Імпортуйте `APIRouter` { #import-the-apirouter }

Тепер імпортуємо інші підмодулі, що мають `APIRouter`:

{* ../../docs_src/bigger_applications/app_an_py310/main.py hl[4:5] title["app/main.py"] *}

Оскільки файли `app/routers/users.py` та `app/routers/items.py` - це підмодулі, що є частиною того самого пакета Python `app`, ми можемо використати одну крапку `.` для «відносних імпортів».

                2, // _dns_domain_bufferp
                3, // _dns_forest_bufferp
                100, // domain_guid.time_low
                4 // _sidp
        );
        when(mockNdrBuffer.dec_ndr_small()).thenReturn(4, 5);
        when(mockDeferredNdrBuffer.dec_ndr_long()).thenReturn(5, 0, 5, // name buffer: buffers, 0, bufferl
                6, 0, 6, // dns_domain buffer: buffers, 0, bufferl

        return message instanceof Smb2QueryInfoRequest
            || message instanceof Smb2SetInfoRequest
            || message instanceof Smb2QueryDirectoryRequest;
    }
}
```

### 4.5 Channel Failover Handler
```java
package jcifs.internal.smb2.multichannel;

import java.util.concurrent.*;

public class ChannelFailover {
    private final ChannelManager manager;

    assertThat(stats.loadExceptionCount()).isEqualTo(0);
    assertThat(stats.hitCount()).isEqualTo(3);

    // duplicate keys are ignored, and don't impact stats
    assertThat(cache.getAll(asList(4, 5))).containsExactly(4, 4, 5, 5);
    stats = cache.stats();
    assertThat(stats.missCount()).isEqualTo(5);
    assertThat(stats.loadSuccessCount()).isEqualTo(5);
    assertThat(stats.loadExceptionCount()).isEqualTo(0);

### `APIRouter` import하기 { #import-the-apirouter }

이제 `APIRouter`가 있는 다른 submodule들을 import합니다:

{* ../../docs_src/bigger_applications/app_an_py310/main.py hl[4:5] title["app/main.py"] *}

`app/routers/users.py`와 `app/routers/items.py` 파일은 같은 Python package `app`에 속한 submodule들이므로, 점 하나 `.`를 사용해 "상대 import"로 가져올 수 있습니다.

### import가 동작하는 방식 { #how-the-importing-works }

다음 구문은:

    assertThat(stats.loadExceptionCount()).isEqualTo(0);
    assertThat(stats.hitCount()).isEqualTo(3);

    // duplicate keys are ignored, and don't impact stats
    assertThat(cache.getAll(asList(4, 5))).containsExactly(4, 4, 5, 5);
    stats = cache.stats();
    assertThat(stats.missCount()).isEqualTo(5);
    assertThat(stats.loadSuccessCount()).isEqualTo(5);
    assertThat(stats.loadExceptionCount()).isEqualTo(0);
