## `uvicorn` の実行

FastAPIアプリケーション上で、`uvicorn` を直接インポートして実行します:

{* ../../docs_src/debugging/tutorial001.py hl[1,15] *}

### `__name__ == "__main__"` について

`__name__ == "__main__"` の主な目的は、ファイルが次のコマンドで呼び出されたときに実行されるコードを用意することです:

<div class="termy">

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

</div>

ただし、次のように、別のファイルからインポートされるときには呼び出されません:

```Python

    /**
     * Gets the installation settings source.
     *
     * @return the installation settings source or {@code null} if none
     */
    @Nonnull
    Optional<Source> getInstallationSettingsSource();

    /**
     * Gets the project settings source.
     *
     * @return the project settings source or {@code null} if none
     */
    @Nonnull
    Optional<Source> getProjectSettingsSource();

## Reduce duplication { #reduce-duplication }

Reducing code duplication is one of the core ideas in **FastAPI**.

As code duplication increments the chances of bugs, security issues, code desynchronization issues (when you update in one place but not in the others), etc.
