então a variável interna `__name__` no seu arquivo, criada automaticamente pelo Python, terá como valor a string `"__main__"`.

Então, a seção:

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

vai executar.

Isso não acontecerá se você importar esse módulo (arquivo).

Então, se você tiver outro arquivo `importer.py` com:

```Python
from myapp import app

                InetAddresses.forString("2001:0000:4136:e378:8000:63bf:3fff:fdd2")))
        .isNotEqualTo(InetAddresses.forString("192.0.2.45"));

    // 2 Teredo addresses differing in their embedded IPv4 addresses should hash to different
    // values.
    assertThat(
            InetAddresses.getCoercedIPv4Address(
                InetAddresses.forString("2001:0000:4136:e378:8000:63bf:3fff:fdd2")))
        .isNotEqualTo(

    browser = playwright.chromium.launch(headless=False)
    # Update the viewport manually
    context = browser.new_context(viewport={"width": 960, "height": 1080})
    page = context.new_page()
    page.goto("http://localhost:8000/docs")
    page.get_by_role("button", name="Item", exact=True).click()
    page.set_viewport_size({"width": 960, "height": 700})
    # Manually add the screenshot
    page.screenshot(

                    <mxGeometry relative="1" as="geometry">
                        <Array as="points">
                            <mxPoint x="800" y="521"/>
                            <mxPoint x="800" y="560"/>
                        </Array>
                        <mxPoint x="803" y="521" as="sourcePoint"/>
                    </mxGeometry>
                </mxCell>

            <button>Send</button>
        </form>
        <ul id='messages'>
        </ul>
        <script>
            var ws = new WebSocket("ws://localhost:8000/ws");
            ws.onmessage = function(event) {
                var messages = document.getElementById('messages')
                var message = document.createElement('li')

    browser = playwright.chromium.launch(headless=False)
    # Update the viewport manually
    context = browser.new_context(viewport={"width": 960, "height": 1080})
    page = context.new_page()
    page.goto("http://localhost:8000/docs")
    page.get_by_text("GET/items/Read Items").click()
    page.get_by_role("button", name="Try it out").click()
    page.get_by_role("button", name="Execute").click()
    # Manually add the screenshot

</div>

alors la variable interne `__name__` de votre fichier, créée automatiquement par Python, aura pour valeur la chaîne de caractères `"__main__"`.

Ainsi, la section :

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

va s'exécuter.

Cela ne se produira pas si vous importez ce module (fichier).

Par exemple, si vous avez un autre fichier `importer.py` qui contient :

```Python
from myapp import app
