### 关于 `__name__ == "__main__"`

`__name__ == "__main__"` 的主要目的是使用以下代码调用文件时执行一些代码：

<div class="termy">

```console
$ python myapp.py
```

</div>

而当其它文件导入它时并不会被调用，像这样：

```Python
from myapp import app
```

#### 更多细节

假设你的文件命名为 `myapp.py`。

如果你这样运行：

<div class="termy">

```console
$ python myapp.py
```

</div>

    unused = HostSpecifier.from(spec);
    assertTrue(HostSpecifier.isValid(spec));
  }

  private void assertBad(String spec) {
    try {
      HostSpecifier.fromValid(spec);
      fail("Should have thrown IllegalArgumentException: " + spec);
    } catch (IllegalArgumentException expected) {
    }

    try {
      HostSpecifier.from(spec);

                : Optional.of(getVersions().get(getVersions().size() - 1));
    }

    /**
     * Gets the repository from which the specified version was resolved.
     *
     * @param version The version whose source repository should be retrieved, must not be {@code null}
     * @return An Optional containing the repository from which the version was resolved,
     *         or empty Optional if the repository is unknown
     */
    @Nonnull

        hyper.encode(buf);
        verify(buf, times(1)).enc_ndr_hyper(12345L);
    }

    /**
     * Verify that the decode method updates the value field from NdrBuffer.
     */
    @Test
    @DisplayName("Decode should set value from NdrBuffer.dec_ndr_hyper")
    public void testDecodeInteraction() throws NdrException {
        NdrBuffer buf = mock(NdrBuffer.class);

  static final int ARRAY_SIZE = 0x10000;
  static final int ARRAY_MASK = 0x0ffff;
  static final Random RANDOM_SOURCE = new Random(314159265358979L);
  static final int MAX_EXPONENT = 100;

  /*

  static final int[] biggestBinomials = {

`__name__ == "__main__"`의 주요 목적은 다음과 같이 파일이 호출될 때 실행되는 일부 코드를 갖는 것입니다.

<div class="termy">

```console
$ python myapp.py
```

</div>

그러나 다음과 같이 다른 파일을 가져올 때는 호출되지 않습니다.

```Python
from myapp import app
```

#### 추가 세부사항

파일 이름이 `myapp.py`라고 가정해 보겠습니다.

다음과 같이 실행하면

<div class="termy">

```console
$ python myapp.py
```

</div>
